How do I stop a deleted purchased apps from continously charging me?
It's likely you made an in-app purchase of some sort of subscription. To check and deactivate the subscription, manage you Apple ID account in iTunes by clicking View My Apple ID in the Store menu.



Enter your password and on the resulting page you should see subscriptions listed under Settings with the number of subscriptions.



Click on the Manage link to the right. There you should be able to cancel any recurrent subscription plans.
