If it is a ban you are trying to appeal,
You have already been told that the EA staff who work on AHQ cannot help you with account-related issues, such as bans.
If you feel you have been incorrectly banned, the only thing you can do is to dispute any action taken against your EA account by following the steps in this article:
https://help.ea.com/en/help/account/information-about-banned-or-suspended-accounts/
I am sorry to hear what happened to you.
As many people have stated your account is your responsibility and if you let someone else use your account and they got the account banned then that is what it is.
Disputing the ban with it was not my fault but it was my friends fault while they used my account will not help you.
In my honest opinion I think you need to talk to your friend about this and what they did on your account and how they are going to make this up to you.
In the future you should not let anyone use your game account for its safety and security.
