AMEX took $847.00 from me knowing full well that they screwed up. I booked a Vietnam hotel through AMEX travel but it turned out to be a AirB/B type place. I was never given any info on how to check-in or contact the landlord from AMEX. 2hrs on the phone with AMEX while sitting in the lobby of the hotel and they finally gave up. I rebooked a different hotel and disputed the first hotel charge. AMEX claims “the hotel provided all needed non-refundable documents, so the charge will stay.” Very disappointing because it wasn’t the Merchant, it was AMEX that never gave the needed info to Check-in.
