Amex reason code C02
Amex C02: Credit Not Processed
What the cardholder is claiming
The cardholder says you owed them a refund, or agreed to issue one, and the credit never appeared on their Amex account.
The evidence that actually wins
Bank analysts skim responses in minutes against a checklist for this exact code. Lead with the strongest fact; never make them dig.
- ✓The credit transaction record showing the refund was already issued, with date, amount, and acquirer reference number
- ✓Your refund policy as it was actually displayed at checkout, plus proof the cardholder acknowledged it before paying
- ✓Correspondence showing no refund was promised, or that the refund request fell outside the disclosed policy window
- ✓Proof the goods were never returned or the service was fully delivered and used
- ✓Documentation of any partial credit already issued, mapped precisely against the disputed amount
The honest read
Start by asking whether you actually owe the money. If you promised a credit and it slipped through your process, issue it now rather than fighting, because losing a chargeback you deserved to lose still costs the fee. The winnable versions are clean: you already refunded and can show the reference number and date, or the request falls outside a policy the cardholder demonstrably saw and accepted at purchase. The common trap is partial refunds, where the member disputes the full charge; document exactly what was credited and when, or the analyst will treat the whole amount as unrefunded.
Nobody can promise you a win; the cardholder's bank decides. What you control is submitting the strongest complete case your records support, on time. Our plain-language guarantees say exactly what that means.
