Account Hacked lost $15

Q u o t e:
So anyway my account was recently hacked and an unauthorized authenticator was put onto it. I pay with my Credit card and i can't cancel the payment and so far I've lost $15 because i cant log onto my account and cancel the subscription.

SO is there anyway to cancel the subscription without having to log onto my account?

You may also want to look into getting an authenticator for your account. It's no substitute for good security habits, but it will help keep them out of your WoW account.
