I made 2 amex platinum cards that require 3k spending on each and I was supposed to get 150k points, I did the spending and I also did the Delta airline credit trick, I was waiting for the points to come in but it never showed up, then I saw online that I got the points and amex took it away the same day. I called amex and they claim its because there was a return from delta, that's why they took away all points. I spoke to the supervisor and I was told that if the system takes it away there's nothing I can do. Any advice??
