There rewards/gift cards used to be bad. As of May there are just plastic waste that will take your money with it to the dumpster. Amex has decided that protecting your money means you shouldn't be allowed to use your money. Amazon, Steam, Uber, Paypal, and every square reader on the planet all are blocked on American Expresses end. They farm support offshore so all they can do is tell you "the transactions were rejected for the safety of your funds," heard the same language from 3 reps and 1 manager about 3 different cards. What's worse is most in person locations also fail now. Its like my money is sitting in a plastic prison taunting me.
