I Paid $15 on Fiverr for a Chargeback Response Letter — Here's What Went Wrong

A few weeks ago, I received a chargeback notification on my Shopify store. A customer disputed a $131.44 order, and the reason listed was “Fraudulent / Unauthorized transaction.” The customer was claiming they never authorized the purchase.

I had tracking confirmation, a partial refund on record, and a clean order history. I figured responding should be straightforward — I just needed someone to put together a professional letter. So I went to Fiverr, found a seller offering chargeback response letter writing, and paid $15.

What I got back was a well-formatted letter that would almost certainly lose the dispute. Not because the facts were wrong, but because the entire defense strategy was aimed at the wrong type of chargeback.

This post is a breakdown of what happened, why the response missed the mark, and what a proper defense for a fraud-coded chargeback actually requires. If you're a Shopify or Stripe merchant dealing with chargebacks — or thinking about outsourcing your response — this might save you from making the same mistake.

The Case: A $131 Shopify Chargeback

Here's the situation. On February 20, 2026, a customer placed an order on my Shopify store — Order #WB-10247, totaling $131.44 for three items. During fulfillment, one item (a posture corrector belt) was out of stock, so I issued a same-day partial refund of $47.49.

The remaining two items shipped via USPS with tracking number 9405511206210453897621. According to carrier records, the package was delivered on February 24 at 2:47 PM to the front door at the customer's address in Houston, Texas.

The customer never contacted me — no emails, no messages through the store, no complaints about the order or the delivery. The first I heard of any issue was the chargeback notification itself.

And the dispute reason? Fraudulent — Unauthorized transaction. The customer (or their bank) was claiming this purchase was never authorized by the cardholder.

That detail — the dispute reason — is the single most important piece of information in any chargeback case. And it's exactly what got missed.

What the Fiverr Seller Delivered

To be fair, the letter looked professional. It had a date, a subject line referencing the order number, and a formal sign-off from “Dispute Management Team.” The structure was clean and the tone was appropriate.

The letter walked through the order details, mentioned the partial refund for the out-of-stock item, cited the USPS tracking and delivery confirmation, noted that the customer never contacted the store, and highlighted our 30-day return policy with free return labels.

On the surface, it reads like a competent chargeback response. If I didn't know better, I'd have submitted it and felt good about my chances.

But here's the problem: every single argument in that letter was designed to fight a “Product Not Received” or “Customer Dispute” chargeback. It wasn't designed to fight a fraud claim.

The Critical Problem — Wrong Defense for the Wrong Dispute Type

This is the part that matters most, so I want to be clear about what went wrong and why.

When a chargeback is coded as “Fraudulent” or “Unauthorized,” the cardholder — or their issuing bank — is asserting that the person who owns the card did not authorize this transaction. Maybe the card was stolen. Maybe it's friendly fraud and the customer is lying. Either way, the core question the bank is trying to answer is: Was this transaction legitimately authorized by the cardholder?

That's a fundamentally different question than “Did the merchant ship the product?” or “Does the merchant have a fair return policy?”

Delivery confirmation, return policies, and the fact that the customer didn't reach out — these are all relevant to disputes about product quality, delivery failures, or refund disagreements. For a fraudulent transaction dispute, the types of evidence that demonstrate the cardholder authorized the transaction include AVS and CVV verification showing the billing address and security code matched, device and IP data consistent with the customer's history, and 3D Secure authentication records.

The letter I received mentioned none of this. Zero authorization evidence.

Think of it this way: it's like going to court for a burglary case, but your lawyer shows up with a defense prepared for a traffic ticket. The documents might all be real, but they're answering the wrong question entirely.

And the Fiverr seller never asked me what the dispute reason code was. They didn't ask for AVS results, CVV verification status, IP address data, or any transaction authentication details. When I later pointed this out, they explained that I hadn't provided that information — which is technically true, but I didn't provide it because they never asked. They started writing before understanding what type of case they were writing for.

Why the Reason Code Is Everything

Visa uses a numeric scheme for its chargeback reason codes. Understanding chargeback reason codes is one of the most essential parts of effective chargeback management. For fraud in a card-not-present environment, the relevant code is Visa 10.4 — “Other Fraud: Card-Absent Environment.”

Merchants can fight code 10.4 chargebacks by providing evidence that the cardholder authorized the purchase or by showing that the responsibility for the fraud lies with the bank or card network rather than the merchant.

The reason code dictates the entire response strategy. A “product not received” chargeback requires shipping and delivery evidence. A “duplicate charge” chargeback requires transaction logs. A fraud chargeback requires authorization and authentication evidence. Responding to one type with evidence meant for another is worse than not responding at all — because it signals to the bank that you don't understand the claim being made against you.

What the Response Should Have Included

For a Fraudulent/Unauthorized chargeback, a proper response needs to establish that the transaction was legitimately authorized. Here's what the structure should look like:

1. An Opening Statement That Addresses the Dispute Reason

The letter should name the specific claim — unauthorized transaction — and state clearly that the merchant is providing evidence of legitimate authorization. Start with an executive summary that ties your defense to the specific network rule or reason code, rather than relying on individual evidence captions to carry the argument.

2. Authorization Verification Data

This is the core of the defense. AVS and CVV verification demonstrate that the billing address and security code matched the card on file. Device and IP data demonstrate that the transaction came from a location consistent with the customer's previous orders. 3D Secure authentication provides a record that the customer completed additional verification. If 3D Secure was enabled and the customer authenticated, that alone can shift liability to the issuer.

3. Transaction Legitimacy Indicators

Documents proving that the IP address, email address, physical address, and telephone number had been used in a previous undisputed purchase are compelling evidence for Visa 10.4 disputes. If the same device and card were used in earlier transactions that weren't disputed, that's strong evidence this isn't true fraud.

4. Delivery Confirmation — As Supporting Evidence

Yes, the fact that the package was delivered to the cardholder's verified address matters. Delivery confirmation showing that the order was shipped to and received at the customer's verified address is a relevant evidence type for fraud disputes. But it supports the authorization argument — it doesn't replace it.

5. Customer Behavior Patterns

Evidence that the customer used the same account, device, or address for previous purchases without disputing them. Under Visa's Compelling Evidence 3.0 framework, at least two core data elements — such as User ID, IP Address, Shipping Address, or Device ID — must match between prior undisputed transactions and the disputed transaction for the evidence to qualify.

6. Evidence Organized and Clearly Labeled

Each piece of evidence should be organized according to the evidence type it satisfies, kept succinct, and combined into files by type. Banks reviewing disputes are looking at dozens of cases. Labeled exhibits (Exhibit A: AVS Verification, Exhibit B: Delivery Confirmation, etc.) make it easy for the reviewer to find what they need.

I'm not sharing a full replacement letter here — every case is different, and a template without context can cause as many problems as it solves. But if the response I received had even addressed the authorization question and included AVS/CVV results, it would have been a dramatically stronger submission. For a general starting point, see our chargeback response letter template.

The Bigger Lesson — Why Most Merchants Lose Chargebacks

I want to be clear: I'm not writing this to attack the Fiverr seller. The letter was well-written, professional in tone, and clearly produced by someone who understands the general shape of a chargeback response. The problem is that “general” isn't good enough when it comes to chargebacks.

And this mistake isn't unique to one freelancer on Fiverr. It's the most common reason merchants lose disputes across the board.

According to industry data, the median win rate for fraud-coded chargebacks is just 36.5%, compared to 56.6% for non-fraud chargebacks. Fraud disputes are harder to win in the first place — and submitting irrelevant evidence makes it nearly impossible.

Merchants win roughly 44% of friendly fraud cases, but their chances drop to just 9% when true fraud is involved. Part of that gap is the nature of true fraud itself, but a significant portion comes from merchants submitting the wrong type of evidence because they didn't tailor their response to the reason code.

Merchants only win about 18% of chargeback appeals overall, even though up to three-quarters of all chargebacks are reported as illegitimate. That gap between how many chargebacks should be winnable and how many actually are won tells you something: the issue isn't that merchants lack evidence. It's that they're not presenting the right evidence for the right dispute type.

A rough but correctly targeted response — one that addresses the actual reason code with the right categories of evidence — will outperform a polished, professional letter that answers the wrong question. Every time.

Chargeback Response Checklist: What to Verify Before You Submit

Whether you're writing your own response, hiring someone on Fiverr, or using a chargeback service, here's a quick self-check you can run before submitting anything:

• Have you confirmed the dispute type and reason code? This should be the very first step. On Shopify, the reason is listed directly in the chargeback notification. If you're using Stripe, it's on the dispute details page. Everything else depends on getting this right.
• Does your response directly address the core question of that reason code? For fraud: Did the cardholder authorize this? For product not received: Was the item delivered? For product unacceptable: Was the item as described? If your response doesn't answer the specific question the bank is asking, it won't matter how detailed it is.
• Have you included the specific evidence that reason code requires? Fraud disputes need authorization data. Delivery disputes need tracking and confirmation. Subscription disputes need terms and cancellation records. Each reason code has its own evidence checklist.
• Is your evidence labeled and organized? Labeled exhibits make it easy for the reviewer to find what supports your case. Banks process a high volume of disputes — dense paragraphs with buried facts don't help.
• Is the response professional, concise, and scannable? Short paragraphs, clear headers, and labeled evidence sections make the reviewer's job easier — and that works in your favor.
• Are you submitting before the deadline? After a chargeback is created, you typically have 7 to 21 days to respond, depending on the card network. Miss the deadline and you lose automatically, regardless of how strong your case is.

If your response can't pass all six of these checks, it's not ready to submit.

What I Took Away from This Experiment

I spent $15 and two days to learn something that could have cost me $131.44 (plus the Shopify chargeback fee) if I had actually submitted that letter. The experience reinforced something I already suspected: the chargeback response process is deceptively simple on the surface, but the details — specifically matching your defense to the reason code — are where cases are won or lost.

The freelancer's letter wasn't lazy. It was just built on the wrong foundation. And that's a problem that no amount of professional formatting can fix.

If you're dealing with a chargeback right now and you're not sure whether your response is aimed at the right target, it's worth pausing before you submit. Look at the reason code. Understand what the bank is actually asking. Then check whether your evidence answers that specific question.

We built a free analysis tool at ChargebackWin that does exactly this. Upload your dispute notification and the evidence you have, and the AI will tell you what your dispute type is, what evidence you need for that specific reason code, and how strong your current case looks. It takes about 60 seconds and it's free.

It won't write the letter for you. But it will tell you whether you're aiming at the right target — which, as I learned the hard way, is the part that matters most.

Frequently Asked Questions

Can I use Fiverr for a chargeback response letter?

You can, but there are significant risks. Many Fiverr sellers write generic chargeback responses without tailoring them to the specific reason code. A fraud dispute requires completely different evidence than a “product not received” dispute. If the letter doesn't address the actual reason code, it will likely lose regardless of how professional it looks. If you do hire someone, make sure they ask about the reason code first and request your AVS/CVV data, IP address logs, and any authentication records.

Why did the Fiverr chargeback letter fail?

The letter focused on delivery confirmation, return policies, and customer communication — evidence appropriate for a “product not received” dispute. But the chargeback was coded as “Fraudulent/Unauthorized,” which requires authorization evidence like AVS/CVV verification, IP address data, and 3D Secure authentication. The defense was aimed at the wrong dispute type entirely.

What evidence do I need for a fraud chargeback?

For a fraud/unauthorized transaction chargeback (like Visa 10.4), you need: AVS and CVV match confirmation, device and IP address data, 3D Secure authentication results, delivery confirmation to the verified address, and evidence of prior undisputed transactions from the same customer. The key is proving the legitimate cardholder authorized the purchase. See our Evidence Guide for the complete checklist.

What is the win rate for fraud chargebacks?

The median win rate for fraud-coded chargebacks is approximately 36.5%, compared to 56.6% for non-fraud chargebacks. Merchants win roughly 44% of friendly fraud cases but only about 9% when true fraud is involved. Submitting properly targeted evidence significantly improves your odds.

How do I know what type of chargeback I have?

Check the reason code on your chargeback notification. On Shopify, it's listed directly in the dispute details. On Stripe, it's on the dispute page. On PayPal, it's in the Resolution Center. The reason code tells you whether it's a fraud dispute, product not received, product unacceptable, or another type — and each requires different evidence. Check our Reason Code Reference to look up your specific code.
