Garena Suspended My Free Fire Max Account Without My Knowledge

I can't get in and my Garena Free Fire Max account—which I haven't checked recently—has been suspended. According to the alert, inappropriate behavior has been observed; nevertheless, I'm not sure how this could have happened. I have spent two years working on this account, which even features the first Evo UMP. It is the account that first drew me in and made me love the game. My pals told me it was active even though I hadn't signed in for some time, hence I assume someone else might have accessed it and created this. This story means a lot to me, hence I really want the suspension to be taken off. Let me to appeal, please. My UID is 8157626 265.
