I believe my account has been hacked
My account has taken a subscription payment i believed i previously cancelled, when i opened my account that i haven’t used for over a year it says someone has played 4 weeks ago and my name has been changed to jova and country to Serbia. There is also a new profile picture of a boy which i am not. I don’t know how someone has got on my account but i have cancelled the subscription and requested a refund for this and changed my password. How is it that someone has hacked into my account and how can i stop this?
