my account is somehow hacked?

so ive been playing since season 4 but i left the game in 2021 i think during the hiatus of me not playing someone somehow got into my account and played it till this day. i still have my email linked so i could get into the account no problem but the facebook and email has changed which was weird?? whats the solution to this i really wanna comeback to this game and i spent thousands on this account😥
