Recover My Free Fire Account Linked to Deactivated Facebook

My Facebook account was deactivated and, as a result, I can no longer access my Garena Free Fire account that was linked to it. I only had this one Free Fire account and it was created and used through my Facebook login on an Android device. Since around November 2025 I have been completely unable to enter my Free Fire account because the connected Facebook account is inactive. I tried several times to contact support, but I could not manage to reach either Facebook or Garena in a way that solved my problem. I have spent approximately 4,000 taka on this Free Fire account, and now I am at risk of losing all my purchases and progress because I cannot log in. I request that my Free Fire game account be recovered or transferred to another login method, or that an alternative solution be provided so I do not lose the money and time I have invested.
