Re: Authentication is temporarily unavailable, please try again later
I am very sorry for your inconvenience.
First off, let me start by saying welcome to EA’s “Answer HQ”. Answers HQ cannot do anything about bans because we are a public forum and can’t do anything account management related, but what we can do is tell you how to dispute and appeal a ban.
To move forward on this, contact the nice folks over at accountdisputes, they can investigate.
1) If you believe your EA account and/or persona has been incorrectly suspended/banned and you would like to dispute this action, please contact support at accountdisputes@ea.com from your registered email address.
2) When sending the email, please include the information requested in the following article: http://help.ea.com/en/article/information-about-banned-or-suspended-accounts/
