Re: Banned for first offense
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 AHQ guide on bans and suspensions :

It is my understanding that you can appeal a ban a number of times.
I have text chat and audio chat switched off and I don't use headphones. I use the ping system to communicate. No way I allow toxic people into my life. But if you do, you cannot retort in kind. It is not "defending" yourself. Not only do you lower yourself to their level, but you are doing what they doing and risk a ban by doing so, which happened in your case. Do not reply and report them.
