American Express C14: Paid by other means
A American Express dispute reason code, what it asks you to prove, and what Do The Proof puts in the response.
What this code means
Paid another way
What the network says wins it
AUTH: no other payment
- Authorization and processing records
How Do The Proof handles it
How long you have to respond
- Merchant response
- 20 days from the inquiry or chargeback notice
There is no pre-arbitration. American Express is both the issuer and the network, and rules after one merchant response; it may then issue a final chargeback.
Merchants in the FR2, FR4 and FR6 programmes get no inquiry at all.
