Product not as described disputes now make up approximately 18% of all fraudulent chargebacks in 2026, up from 15% in prior years, fueled in part by the rise of social commerce, where product imagery can diverge from physical reality.

That communication forms a crucial part of your evidence package.
Necessary documentation to include in your representment:
How to write a chargeback response template letter to the bank for this dispute type:
Subject Line: TRN #XYZ, CHG-BK CODE: XXX X
To whom it may concern,

Pro tip (2026 update): Mastercard's updated dispute guidelines now allow merchants to submit video evidence of product demonstrations or unboxing footage as supplemental documentation in "not as described" cases. If you have product demo content, include a link or file attachment in your chargeback rebuttal letter example.
This category of fraudulent chargeback claims is represented by the following reason codes:
Unauthorized transaction chargebacks account for nearly 35% of all chargeback reason codes in 2026, the highest share of any category. The win rate for this particular reason code remains slim because disputes generally reference fraud claims. Mastercard and Visa will rule in favor of the cardholder automatically if they truly fell victim to fraud.
With that in mind, contact the cardholder before initiating representment. Send them an email sharing the tracking details of the item you shipped. That communication serves as one of the most valuable pieces of evidence to help you win.
In 2026, 3DS2 (3D Secure version 2) authentication data has become a near-decisive factor. If the transaction was authenticated through 3DS2, include the authentication response code in your chargeback rebuttal letter template; this shifts liability back to the issuer in most cases.

Regardless of which chargeback template you're using, the strongest rebuttal packages share a few common traits:

Using a chargeback response template manually is a solid starting point, but it has real limits at scale. If you're processing more than 50 chargebacks per month, manual representment becomes unsustainable. Each dispute requires research, customization, and precise timing, and a single missed deadline costs you the case outright.
Automated chargeback management tools, like Chargeflow, give you flexibility and control over the entire representment process. Instead of doing painful labor manually or juggling multiple programs, chargeback automation provides a single platform that uses AI-powered fraud detection, network-specific evidence mapping, and automatic deadline tracking to fight disputes on your behalf.
In 2026, merchants using automated chargeback management report win rates up to 4x higher than those handling disputes manually, and recover significantly more revenue from friendly fraud, according to Chargeflow's merchant data.
A strong chargeback response template should include a subject line with the transaction number and chargeback code, a brief opening paragraph stating your intent to contest, clearly labeled evidence exhibits (order records, shipping confirmation, customer communications), and a closing request for a ruling in your favor. Each chargeback template letter should be tailored to the specific reason code of the dispute.
A chargeback rebuttal letter, sometimes called a representment letter, is the formal written argument you submit to the card network or issuing bank contesting a chargeback. It presents your evidence and explains why the transaction was legitimate. A well-written chargeback rebuttal letter example will clearly reference each exhibit and directly address the cardholder's stated reason for disputing.
The general structure of a chargeback dispute template remains consistent across reason codes, but the evidence you include must be specific to the dispute type. For example, a "not as described" chargeback template requires product images and your return policy, while an "unauthorized transaction" template requires authentication logs and AVS results. Always match your evidence to the applicable network rules.
At a minimum, merchants should maintain chargeback response templates for the four most common dispute categories: physical goods not received, digital goods not received, not as described, and unauthorized transactions. High-volume merchants may also want specialized chargeback template letters for subscription cancellation disputes and credit not processed claims.
As of 2026, Visa's standard representment deadline is 20 calendar days from the date the chargeback was filed. Mastercard typically allows 45 days. AMEX and Discover have their own timelines. Regardless of how strong your chargeback rebuttal letter template is, missing the deadline results in an automatic loss, so tracking deadlines is non-negotiable.
No chargeback response template guarantees a win, but using a well-structured template significantly increases your chances. The card networks review disputes based on the quality and relevance of your evidence against their specific chargeback reason codes and rules. A strong chargeback rebuttal letter example with complete, well-organized documentation consistently outperforms improvised or incomplete submissions.
The most persuasive evidence in any chargeback rebuttal letter is documentation that directly contradicts the cardholder's claim. For delivery disputes, this means carrier confirmation with GPS or photo proof. For digital goods, it means server logs and redemption timestamps. For unauthorized transactions in 2026, 3DS2 authentication codes are often decisive. Always organize your evidence chronologically and reference it clearly in your chargeback dispute template.
A proper chargeback template letter should have a clear subject line identifying the transaction and reason code, a professional salutation ("To whom it may concern"), a structured body with sequentially labeled exhibits, and a polite but firm closing requesting a ruling in your favor. The format of your chargeback response templates should be clean, professional, and free of emotional language; you're presenting evidence, not arguing.
