Purchased $100 AA GC on 6/18 and still have not received the reimbursement. This is for the Gold premier reward card. I bought the 2x GC for same amount with my platinum card few months ago and got reimbursed 3 days after. The only different I am aware of is that at the time of the GC purcahse on the Gold card, I have a negative balance from a return (AMEX owns me some money). Would this be the reason why It did not trigger reimbursement for the GC? Is it worth while to try again?
