An unknown email linked to My account

I use to play apex legends before then i deleted that game for some reason.... and today i downloaded it and i found that an unknown email is linked to my EA account.... i tried many times to recover my account but nothing worked. when i log in then it shows my original email logged in but not linked and in game it shows that some unknown email is a already linked to your game account.
I am not able to get my game account access in anyway..
Please prioritize this case
