My Facebook-Linked Garena Free Fire Account Was Hacked

Hi Garena, I am really glad that I got a chance to talk to you. I just need help because my Free Fire ID was linked to my Facebook account and now it has been hacked 😭. The hacker has changed the Gmail and everything, and I don't have any access to my account anymore. Can you please help me get my account back? UID - 1237963621




I accidentally accepted it and recovered the Facebook account through Google. How can I fix it?
