I booked a Hotel through AmEx Travel using their $100 cash back promotion. Now I want to cancel the booking and it won't let me do it online since it is less than 5 days now to travel date. The chat option says available "7AM - 7PM" on a popup but there is no chat window to start chatting. I am on hold on the phone for over 30 minutes now.
This is really poor support experience from American Express. Just venting.
If you have one of their more premium/high-end cards (like Platinum or Centurion) that has a dedicated concierge service, give them a call. I found them to be quite helpful before.
