Chatted with Amex regarding my purchases on 1/31. Asked them about these charges that are usually reimbursed within 2-3 days (didn't say these were for GCs, obviously) and their answer was generic (as I expected): that it usually takes 2-4 weeks to receive them back.
I give up. Will buy another $100 using my Gold and if that works will do the same with Plat and again with Aspire.
