Lost Free Fire Account

My Free Fire game account linked to my Facebook email account has been lost and I can no longer access it. When I open Free Fire and try to log in with the same Facebook account that was previously linked, the game now asks me to create a new Free Fire account instead of opening my old one. My lost Free Fire ID number is 908430813. This problem started around five months ago. Since then I have tried many ways to recover my old account, but I have not been successful. I did not add any recovery address to my email account, so I cannot use recovery options to restore access. I kindly request your support to help me log back into my old account linked to Facebook, or to restore access to the Free Fire ID 908430813. I also request that you check if there has been any unauthorized access or change on the connection between my Facebook account and my Free Fire game account, and secure my account so that I can use it safely again.
