Aweful experience! The app does not except my new password and after 3rd attempt it revokes with error message giving a wrong phone number for American Express customer support. Also it is so difficult to reset it. Inhumane and unhelpful customer support. I went over my limit, and paid off all my balance, but they cannot undo negative credit activities they sent out to Expedia. They act as scammers, and they never fix any errors in their website and app. I would never recommend using their services. You better off using Capital One or other credit cards with better rewards and forgiving programs
