sounds like you are banned.

in addition to @satfreaktom264's answer (thank you for that!), I'd suggest to read the rules of the game (again), independent of whether your ban is justified or not; in order to avoid to be banned in the future again. you will find the rules here: Know the rules in EA SPORTS Madden NFL Football
by the way: I recently wrote about my thoughts on bans/suspensions in Madden in this forum. I'd be interested in your feedback if you would like to read my post: https://answers.ea.com/t5/Game-Information/About-coin-buying-bans-and-the-lack-of-opportunities-to-earn/m-p/10289131
I hope your ban will be lifted soon. good luck!
