Still waiting even though it says it's been delivered

I ordered an instant iTunes voucher about an hour ago, had to go through a lot of verifications etc but all of that was fine. Finally got my verification email saying I won't have to go through it again and that my voucher would be emailed to me in 10 minutes but, 40 minutes later, nothing has happened. I checked my account details and order status and it even says my email has been delivered. It definitely has not. Customer service won't respond to me. Either they can sort this out ASAP or I'm putting this down as a scam site. My stars will be increased if this can be resolved quickly.

Edit: After some complaints they resent me the email a few hours later containing the code I needed. It works. I have upped the stars from 1 to 4 because it was a fast transition.
