Q: Why is my credit card being charged

You may be able to 'report a billing error' or access the other information you seek through contacts

at Apple by using the main web site and sub-sections. Or see if the information linked in the Support

page for iTunes helps. There are a lot of possible items to sift through, though only one need work...

•iTunes Support - Main - Accounts, etc:

http://www.apple.com/support/itunes/account/

See the 'Billing' section in iTunes Support -- among items there, note:

•Report a Problem:

https://reportaproblem.apple.com/

Read here before attempting to get refund or other course of action:

•iTunes Store charges on credit and debit card statements - Apple Support

iTunes Store - unrecognized charge - action form (see above, first)

https://getsupport.apple.com/ServiceOptionAction.action

In any event...

Good luck & happy computing!
