Free Fire Account Hacked and ID Lost

I am writing about a serious problem with my Garena Free Fire account on the Indian server. My Free Fire ID is 1229226577. This ID was being used by my brother, and a few months ago it was hacked and is now being used to hack and disturb other players. Because of this hack, I no longer have access to the account on my phone and I cannot log in or use it in any way. This account has had many top-ups and in‑game purchases made on it over time, so it is very valuable to us. Now it is completely out of our control and is being misused by someone else. I am very upset and worried because the account is linked to us, but we do not have the original registration details such as the email or phone, since my brother was managing it. I kindly request that my Free Fire ID be recovered and returned to me with full access, and that you investigate and stop the person who is currently misusing it. I want to use my own account again safely and fairly and not have it used to harm other players. I ask you to please review this situation urgently, secure the account, and help me get it back.
