Gmail Compromised and Free Fire Max Account Link Changed

I am using Gmail on my Android device and recently my account security has been compromised, which has also affected my linked Free Fire game account. Although I can still log in to my Gmail, I noticed that tomorrow at around 4 PM someone changed the Free Fire ID that was bound to my Gmail without my permission. After this unauthorized change, my Free Fire account link was replaced with another person’s ID, even though I did not share my account details or approve any such action. I have not yet contacted Google or Garena/Free Fire support about this situation, but I am very concerned that my Gmail may be at risk and that the hacker may continue to use or change my data. My request is that the unauthorized Free Fire binding be removed from my Gmail account and that my account be secured as soon as possible. I would like all suspicious activity on my Gmail to be investigated, my account protections to be strengthened, and, if possible, my Free Fire connection to be restored safely to me, not to the person who carried out this unauthorized change.
