American Express F24
No Cardmember Authorization
← All reason codes
What the cardholder is claiming
The cardmember says they did not take part in the charge and Amex finds no valid authorisation behind it. Evidence tying the cardmember to the purchase answers it: an earlier undisputed charge on the same account, a delivery they signed for, or their use of what was bought.
