Q: I have a charge on my credit card, but I didn't purchase anything on that date. How do I get it off or refunded back to me?

You've checked the purchase history on your account ? You didn't have any pre-orders and/or auto-renewing subscriptions that were due ? If you log into your account on your computer's iTunes via the Store > View Account menu option, you should then see a Purchase History section with a 'see all' link to the right of it. Click on that and you should then see a list of your purchases.

If you don't recognise the charge, and nobody else has access to your account or devices and may have made it, then try contacting iTunes Support : 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
