Meh, my only experience with Amex customer service is this: I rented a car for 12 days. On day 5, as I try to drive to my own wedding, the car doesn't start. The rental car company refuses to help. I eventually get the car back to them on day 6 after AAA tells me the car should not be rented out at all. The company refuses to return any money, so I try a chargeback through Amex. They refuse the chargeback all three times in their dispute resolution process, even for the six days I paid for but didn't use. After begging, the rental company returns the cost of 6 unused days. I never see any other money, not for the 1 day the car was disabled and no compensation for ending up late to my own wedding. Shit happens, but if Amex can't even refund me my 6 unused days in this situation, I don't know what they can do.
