I have an interesting datapoint. I received an excess clawback.

1. 1/28/23 Made a FHR booking for ~$255
2. 2/2/23 $200 Credit received
3. 2/9/23 Reservation cancelled and refund was posted as of this date
4. 2/11/23 $255 Clawed Back. The $255 charge shows Amex Hotel Credit under additional information

Chatted with Amex after a few days, they said to give it two weeks and if it hadn't been resolved to chat again and they'd get it credited. Chatted with them 2/26, they initiated a dispute. However what they disputed was my 1/28 purchase and not the 2/11 clawback.

They put the dispute in for the full amount with a temporary credit of $255 saying it would get correctly adjusted for the $200 hotel credit received when completed. That did not happen. 3/14 the dispute was closed, the $255 charge was added back to my account backdated to 1/28. Their email stated "Please be advised that AMEX Fine Hotels and Resorts has also issued credit(s) to your account in the amount of $255"

I called them a couple days later, they said no worries it would get correctly resolved and that they indeed did understand the situation. I don't believe they truly do. Nothing has happened in relation to the excess $55 clawback still charged to my account.

There is a tracker on the website for this credit. It shows $0 received for the year. I used my 2022 credit in December and that stay was completed in January.

So my cancellation has cost me $55 and all kinds of time trying to explain this to them (with getting another family member on the phone). I also have a negative MR balance at the moment from the temporary credit subtracting MRs that were never received from the clawed back charge.
