[2021] A ban??

Hey, we can't share much in the way of specifics but I recommend reaching out to support to investigate what happened.

From your description it sounds like your account may have been compromised and used by a bad actor while you were away, but that's just speculation from the info given. Be sure to check for any mails from EA since you stopped playing, too.
