In order to request a refund from Apple, you will need to contact them directly (only Apple can issue the refund). Here is how to submit a refund request:
1) Find your in-app purchase records. Check your email for iTunes receipts or use a computer to sign in to your iTunes account and view your Purchase History. Here is a link that will help you locate your in-app purchase records:http://support.apple.com/kb/ht2727?cid=CDM-US-DM-P0015957-321943&cp=em-P0015957-321943&sr=em
