Happened to me at 3 different hotels in Europe this summer. There was nothing quick about getting AMEX to rectify it. I had to call multiple times. A case was opened a month ago. Two days ago, I was told they hadn't finished their investigation. What is there to investigate? The hotels are Marriott brands. Then I was told that one of them was a Design Hotel, not a Marriott hotel. Uh, it's one of Marriott's 29 brands. As of today it has been handled though with no apology on AMEX's part. The agent said that the points I was owed were all the bonus that she could give. Huh? I earned those points, there was no bonus involved. Can you tell I feel a bit testy about the process?
And welcome to posting, sea-faring. I'm impressed that 14 years on, you remember your handle and log in information. Well done.
