Banned EA account for no reason

Hi All!

I bought a used ps5 console a week ago. 

I created a new account and started play fifa UT. I am a casual player. Played some games, did the sbcs, was grinding the new cards. 

However a few days later I got a full EA account ban. 

I tried to dispute and wrote them an emai (if you have a banned EA account you can't find the chat option with them, I tried every trick but no...) but we all know EA, they wasn't too helpful at all, just sent me a copy paste message of the T&A 2 days later that their decision will remain. 

I really want to know the reason I got his full EA account ban, because I went through on a T&A and I did nothing wrong.

At least I want a bit more explanation from their side what's went wrong to avoid it in the future.

It's so annoying when a user needs to suffer because the EA algorithm detect something what not even happened.
