We are fellow users here on these forums, you are not talking to iTunes Support nor Apple.

Have you checked your account's purchase history : See your purchase history in the iTunes Store - Apple Support

If you've been charged for something but not received it then yry the 'report a problem' page to contact iTunes Suppor : http://reportaproblem.apple.com

Or you can try contacting 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.

I will go to Apple, thanks
