My account was banned suddenly, with no email from EA
All the available information relating to your ban would have been communicated to you via the email associated with your EA account. You mention that you may no longer have access to that email.
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:

There is also this AHQ guide on bans and suspensions :

It is my understanding that you can appeal a ban a number of times.That said, you are ultimately responsible for your account, and the actions of anyone you let use it.
It's unlikely that you would have recieved a ban for being matched up with random players.
