Garena Free Fire Account Permanently Suspended for Abnormal Activity

I am writing about the permanent suspension of my Garena Free Fire account on Android. My in‑game UID is 1943370748. Around 1–2 years ago my account was banned, and since then I have been unable to access it. When I try to log in, I see a message saying that there are abnormal activities on my account and that it has been permanently suspended. I do not know exactly why my account was banned. The only relevant detail is that I had given access to my account to a friend before the ban, and after that my account was suspended. I did not receive any clear explanation or detailed information about what specific rule was violated. I kindly request that my account be reviewed again and reactivated if possible. If reactivation is not possible, I ask for a detailed explanation of the exact reason and evidence for the ban so that I can understand what happened and avoid such issues in the future.
