Please Recover My Facebook Account

I have a problem with my Free Fire account with player ID 1977825543. It was linked to my Facebook account. I had given my account to someone else to play, and now my account does not appear when I log in with Facebook. It looks like someone has bound my account to another login, so I cannot access it anymore. The last time I could log in with Facebook to this account was on the 28th of last month. Since then I cannot see or open the account through Facebook. I have spent around ₹40,000 on this account, so losing it is a big loss for me. I have not contacted support before. I request that you recover my Free Fire account with ID 1977825543 and give me access again through my Facebook login, and remove any unauthorized binding made by someone else. I am ready to provide any proofs needed that this is my account.
