Cant login into my old account

A long time ago I linked the account to Facebook, but now I can’t access it anymore no matter what I try.

I try to ask before but dont get any answer

I still remember some details about the account, but the Facebook connection seems to be broken or unavailable, and I’m unable to log back into the game.

Has anyone had a similar problem before, or knows a way to recover an old account that was connected through Facebook? Any advice would be really appreciated.

Thanks in advance!
