What if I don't have a receipt?
Apple only sends receipts every once in a while... So how do we find this link if we don't have the email receipt?
You don't need the receipt to report a problem. Go here:
http://www.apple.com/support/itunes/contact/
and follow the instructions to report any issue to the iTunes Store. If you need the order number and date, you can get that from your Purchase History:
