Re: You may have mistakenly banned my account.
The EA staff who work here on AHQ cannot help directly with account-related issues, such as having been hacked. If you feel you have been hacked, the only thing you can do is follow the steps in this article:

FYI it might be as good idea to immediately turn on 2 factor authentication on your account, when you get it back, and change your EA and account associated email password.
