I Cannot Access My Free Fire Account After My Facebook Was Hacked

My Facebook account was hacked, and because of that, I can no longer log in to the Garena Free Fire game. The hacker changed the email, phone number, or password linked to my Facebook account, so I can’t recover access. I don’t know what to do and need urgent help. Please solve my problem. My account has been hacked, and I can’t access it. My UID number is 365540027. Please, sir, I kindly ask you to return my ID.
