I Lost My Free Fire Account After a Cobra MP40 Scam Website

I have been facing a serious problem with my Free Fire account linked to Facebook on my Android device, and I am requesting support from Garena to recover my old account. My Free Fire UID is 1735984650, and my in‑game name is Sivanantham. My last purchase on this account was the Cobra MP40. Around three years ago, a player in my lobby told me that I could get a Free Cobra MP40 upgrade token through a Google redeem on a certain website. I visited that website and logged in with my Facebook ID as instructed. It turned out to be a scam. The person cheated me, stole my account, and changed my Facebook recovery email and code to his own Gmail, so I lost control of both the Facebook login and my Free Fire account. Since then, I have not been able to access my old Free Fire account. I have tried to get help but received no response so far. I am very upset that my account, on which I spent money and time, especially for the Cobra MP40, was taken from me in this way. I kindly request that my old Free Fire account with UID 1735984650 and username Sivanantham be recovered and returned to me, or that you guide me clearly on the steps and documents required so I can prove my ownership and regain access.
