Hi @Kauer.
I'm sorry, but account bans are not something we can help with here on Answers HQ. The Terms of Service team would need to review the account and determine if the ban can be overturned.
For more information on how you can set up a case with them check out the EA Help website. The TOS team will review the account and follow up with you via email as soon as they can. I'm afraid we don't have a way of seeing how long that may take. It can vary as they review each appeal on a case-by-case basis.
