my Battlefield One account was banned for no reason and received no email

why my Battlefield One account was banned for no reason and received no email and no record of the banning！！！！！

My account was in normal use yesterday, after a short hangout I found that I couldn't access the server and found that my account had been banned by fair fight, I didn't do anything in the middle of it. I didn't do anything during the process. I didn't receive an email about my account being banned, and there is no record of my account being banned in ea help. So I would like to unblock my account please
