You aren't charged for having an iTunes account, and it's not possible to cancel or delete an account - all you can do is remove any personal info from an account and stop using it, but any content that was bought/downloaded with it will remain tied to it.
If you have auto-renewing subscriptions then there are instructions on this page for managing and stopping them : http://support.apple.com/kb/HT4098
If you've subscribed to iTunes Match and want to cancel it the subscription then you can try contact iTunes Support via this page :http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Purchases, Billing & Redemption
If you are referring to some other charge ... ?
