American Express Customer FAQ

You can change your bill due date by logging in to your American Express account online or through the Amex App. After logging in, navigate to the "Account Services" tab and select "Payment & Credit options". From there, choose "Change Payment Due Date". Please note that not all billing cycles are available. The changed date must be at least 20 days after the closing date of the current billing cycle and up to 51 days away. Changes may not apply until your next statement, and you can only change your payment due date once every three months.

If you suspect fraudulent activity on your American Express card, you can contact American Express directly by calling their international collect number +1-336-393-1111. To avoid international charge, they suggest the best way is to call through the local operator. Make sure you have your card details with you when you call in order to expedite the process. They are available 24/7 to assist you. Please remember it's important to report any suspected fraudulent activity as soon as possible.
