Getting a refund can be difficult. Apple does not share any user information with App developers This is great for user’s privacy but it means as an app developer we have no way to issue you a refund.
Apple has a very strict and confusing refund policy that you agreed to when you set up your iTunes account. Click here to view Apple’s refund policy http://www.apple.com/legal/itunes/us/terms.html.
You will need to contact Apple directly for a refund.
Here are two links to Apple support and their US techincal support #:
http://support.apple.com/kb/HT1933 (This link shows you how to report a problem and request a refund, from within iTunes.)

Apple’s first response will be to deny the refund and refer you to the app developer. You will need to be insistent: Apple collected your funds by charging your credit card, the app developer did not. As the app developer we have no record of this sale. You will most likely have to request to speak with a supervisor. It has been our experience that they will eventually give in.
