Restore My Permanently Banned Free Fire Account

I am a Garena Free Fire player on Android and my account has been permanently banned without a clear explanation. The banned account was in the Bangladesh region with the nickname OP Mizan and UID 2198708460. The suspension message in the game states that there were “abnormal activities” and that the penalty is permanent, but I do not know specifically what I am accused of. This ban happened around more than three years ago. I would like my situation to be re‑examined in detail and the exact reason for the ban to be checked again. I am requesting that my game ID be unbanned and that I be allowed to access my account again if possible. If there has been any mistake or misunderstanding, I kindly ask you to correct it and restore my account.
