Oh no that is not good. Unfortunately here on the forum we cannot assist with account actions here on the forum accept for providing some advice and tips you can use.
First things first you will need to contact EA help and resecure our account you should also contact your e-mail provider for the e-mail linked to the EA account and resecure that as well.
If you believe you have been hacked take appropriate measures to secure your account and associated e-mail account https://help.ea.com/en-gb/help/account/secure-hacked-ea-account/
After you have done that then you will need to contact the EA ToS team about the ban
If you believe that a sanction (Suspension/Ban) placed on your account was by mistake you should reach out to the Terms of Service team https://help.ea.com/za/help/account/information-about-locked-or-banned-or-suspended-accounts/
Make sure you include the information about the hacked account when submitting the ban appeal.
