I got permanently banned over my brother

Hey there,

It isn't possible to help you with bans or suspensions here on Answers HQ.
If you think the ban or suspension was a mistake, you will have to contact EA directly: 

1. Go to https://help.ea.com/en/contact-us/
2. Make sure to log in to the account you've been banned or suspended on.
3. Select the product that your account was banned or suspended from.
4. Choose your platform.
5. Select 'Manage my account', then 'Banned or suspended account'.
6. Fill out any additional details.
   • For example, it might ask you if you are playing the game through an EA Play membership.
7. Click 'Select contact option' at the bottom of the screen.
8. Click the + sign.
9. Fill out the attached web form to give us all the details about your ban or suspension.

The process of reviewing your ban or suspension might take some time. Only fill in this form once, sending in more appeals isn't going to speed things up.
You can keep track of the case you made over here: https://help.ea.com/en/my-cases/

This is your ban history: https://help.ea.com/en/my-ban-history/
Please keep in mind: your ban history does not show all bans and suspensions
