@bionicgrampas if you are not already aware of it, I would at least like to point you to this info thread about bans/suspensions and how to dispute them:
https://answers.ea.com/t5/Technical-Issues/INFO-Account-Suspensions-or-Bans-in-Madden-NFL-21/m-p/9837207you will also find a link to the Madden rules there. maybe it is a good point in time to read these rules, independently of whether your ban is justified or not. just to reduce the risk of facing a ban in the future again.
I recently wrote my thoughts about bans in this forum because I've read so many similar stories (like yours). maybe you are interested in reading it? I would be thankful for any feedback.
