Free Fire Old Facebook Account Opens New Level 6 Profile Instead Of Original

I have been having a serious problem with my Free Fire account that is linked to my old Facebook account. My Facebook account is old, but when I log in to Free Fire with it, the game opens a new account instead of my old one. Previously I had an advanced Free Fire account, but now it only shows a new account with level 6 and my old data is missing. I noticed this problem about 5 months ago and since then I have not been able to access my old progress. I request that my old Free Fire data and account be restored to my Facebook login, and that the wrong new account be removed or separated so I can use my original account again.
