Request to Unban Free Fire Account

My Free Fire account, which has the UID 1346790819 and the in-game name KILLER, was hacked about a month ago. When I tried to get it back through Facebook, I saw that it had been banned because of what the unauthorized user had done. Since 2019, I've played legally and never used cheats. I've also put money into my account by making regular purchases. I think the hacker's acts, not mine, led to the ban. If you need them, I can give you records. Please look into my case and let me go. It hurts me a lot to lose this account because it's important to me. Thanks.
