FF Account Hacked and Nickname Changed Without Permission

I have a Free Fire account on Garena that was accessed without my permission and I believe it has been hacked. My in‑game nickname is SRS.YT and the account is linked via Facebook. After the hacking incident, the nickname and login details were changed and I can no longer access my account as before. This account is important to me because I spent a lot of time and effort to reach my current level and collect my in‑game items. I am very concerned that my progress and all the items in this account may be lost or used by someone else. I kindly request that my Free Fire account, linked to my Facebook, be recovered and that my access be restored. I would like the unauthorized access to be investigated and the account to be secured, and I am ready to provide any additional information or verification you may need.
