Garena Blocked Me from Accessing My Free Fire Max Account Linked to Facebook

My Free Fire Max account has been hacked, and I need assistance with recovery. I can't access my Free Fire account because it's linked to a Facebook account that I no longer have access to. Below are the details: My Free Fire UID is 1474776155, and I have logged in previously. When I attempt to log in now, it creates a new account instead of accessing my previous one. I would greatly appreciate assistance from Garena in recovering my original account so that I can resume using it. I would appreciate your prompt assistance in resolving this issue. Thank you very much!
