Call of Duty and Activition Unfair Ban

Hi everyone I've been playing Call of Duty Warzone for a few months now and today 2020/08/23 I've been banned for no apparent reason.

I'm truly disappointed in there services and I've also spent money on the game itself and now I cant even play it. I've waited 2 hours to get on activation support and they couldn't help me and worst of all the support consultant just ended my chat with him without warning or help.
