Re: I appealed my EA account 3 times but could not lift the ban.
If you have strange login records it would lead me to believe that your account may have been compromised/hacked.
You will need to first get your account re-secured along with the associated e-mail before attempting to lift the ban. See below for links to get that done.
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/
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/
Contacting EA help https://help.ea.com/help/faq/using-ea-help
Good luck.
