I was 3 day banned during a powerlevel, and I emailed blizzard and said I clicked a keylogger, and I included all my info and they said sorry you purchased a leveling service, we can't lift the suspension. So I talk to the power leveling company, and they ask for my acc and pw to verify, I give them it and they say they can't do anything, all they can do is continue lvling after the ban. I said I don't want them to continue the leveling, because they'll just get it permanently banned, and they say they can't do anything for me.
What should I do, if anything? If I file a chargeback will I win, and what should I say?
