iTunes charges

If it is a recurring charge for the same amount, see: View, change, or cancel your subscriptions - Apple Support

If that doesn't help, see the following instructions. They include information on contacting Apple Support if the other steps don't help: If you see apple.com/bill, itunes.com/bill, or an unfamiliar charge on your statement - Apple Support

See my previous reply. This is primarily a user-to-user support forum; other Apple users like you. We don't have access to information on your charges but the steps outlined in my previous reply should resolve the issue.
