I can't chat with online staff of ea,I need someone to confirm my account.

@Clarou1970 live chat will not discuss bans.

All the available information relating to your ban would have been communicated to you via the email associated with your EA account.

You can also check out your ban history here, but please note not all bans may appear here:

The EA staff who work here on AHQ cannot help you directly with account-related issues, such as bans, only the TOS team can help you.

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/

There is also this EA guide on bans and suspensions :

It is my understanding that you can appeal a ban a number of times.
