I just got off the phone with AMEX and told them this was a pet fee that I've paid for before last year. I bought my $100 GC 2/22 and was not credited. Gentlemen said I will see my credit in 5 business days. I got lucky. Guess will have to purchase lower amounts next time. That seems to be working for others.
I don't recall the amount being the issue. The changed the way AA GCs are displayed as a charge to Amex. I don't see how a lower amount is going to change that.
