Account ban

My account was inexplicably banned. I have been waiting for almost a month and submitted appeals twice, but EA hasn’t responded to me at all. As an ordinary player, I have played the game for nearly 800 hours; the account level was earned by me bit by bit. I reached almost level 400, and I also purchased several seasons of the battle pass and skins. I really don’t understand why I would be banned if my KD last season was only 0.8. I have not engaged in any cheating, and I have never logged into my account from an internet café or other locations. EA's cold handling of this situation is truly disheartening and disappointing! As an ordinary player, I don’t even have the proper appeal channels due to an incorrect linked email and can only appeal by paying. This is really distressing. I feel disappointed in EA and in this game, which seems to be deteriorating every day! If I had engaged in any cheating, my life would have been unfortunate starting this year.
