Recovering Stolen Free Fire Progress and Lost UIDs via Garena Support

I am writing about a serious problem with my Free Fire account. My account was hacked, and I lost access to it even though it is very important to me. My Free Fire UID is 863619999, and I was playing with the profile shown in the attached screenshot. The account was linked to my Facebook account. Around 3 years ago I started to notice unusual activity in the game, which showed that someone else had logged into my account without my permission. After that, I completely lost access and have not been able to log back in since then. I have already tried the basic recovery steps and the usual methods you recommend, but none of them have worked. I still cannot get into my Free Fire account and cannot use the items and progress I earned. I kindly request that you investigate my Free Fire UID 863619999 and help me recover my hacked account or provide access back to me as the rightful owner.
