I got ban on 18/Mar/25 at 3:21 PM UTC While i did not play at time

Did they actually resolve this? I was just banned for life for cheating when I definitely was not and they just denied my appeal within a few hours with a prewritten response and no explanation whatsoever. The forums are seemingly the only place to get a response from a human, and they just say to submit an appeal, where it gets denied with zero explanation.

You don't need to prove anything, in this case! Our Terms of Service team will just take a look back through their own records to verify what took place. 

The only thing you'll need to do here to get that process started is create an appeal.

i checked 2 step verfication and change new password for both EA account and my email. But I don't know how to prove to them that I wasn't playing at that time to get the ban lifted.

Make sure two step verification is enabled in your account, change your e-mail password then your game password.
