what do i do?

guys, if you get scammed by the your fav game what do you do? so i got scammed by this game (i wont say the name to not be rude) ,so the scam i got was that i needed to pay the game the amount of time i played it in hours and i played it for 3 months, so now every single thing i try to type/send/play is only that game's name, so i think it hacked my account or something, please tell me what to do bc i cant enter my pc anymore.
