Two of my Citi credit cards were shut down. The Citi premier card and the American airlines business platinum card. I'm very disappointed.

I used mostly the citi premier card about 900k spend over the course of 2 years, and only about 30k spend on the American airlines card over 1 year. I got a call from citi 1 year ago that my card was flagged for review and answered their questions very honestly, I really did not think I was in violation of any of their terms or conditions. Then recently received another call about 3 months ago. This time around got some weird questions which I also answered honestly. They asked me where my credit card payments were coming from, and I told them they were coming from my personal bank account (which they were). Then they asked me why I was making my payment in pieces and not just paying the whole balance at the end of the statement. I told them and this is true that I don't want a large debt to build up so usually make payments as I use it (ie 2-3 payments a week). Apparently they don't like that and prefer you just make one payment at the end of your cycle. In any case on 1/7/2021 both cards were shut down and I received 60 days to use or lose my Citi premier points.

Please also note that I couldn't ransfer the points to any partners after credit card shutdown. Hope this helps someone in the future. Also i wanted to mention that I manufactured spend through gambling websites and I don't actually think its even MS because I really did use the websites as gambling websites require 1x rollover (meaning you have to bet your funds that you deposit).
