To cancel a Marriott Bonvoy Brilliant credit card, call customer service at 1 (800)-528-4800. Cardholders can also cancel an account in person at an American Express branch, or by mail.
Be aware that if there’s a balance remaining on the canceled account, you will still need to make at least the minimum payment every month until the balance is paid in full. In addition, you will forfeit any unused points, so be sure to redeem them before you cancel the card. You will also need to update the payment method for any recurring charges linked to your Marriott Bonvoy Brilliant card.
