Typical chargeback scam. They charge your card (or paypal) for the code, three days later you get an email saying they cant supply the code, then because its only $10.99AU they hope you couldn't be bothered to contact your card issuer for such a small amount.
Time this by 1 or 2 hundred customers a day and you can see how much money they can scam.
I'm sick of emailing them now because they keep asking for more and different information, to find my suppoed payment, so its off to the bank, and the QLD police e-crime department to dob them in
...and get MY $10.99 back, Please do the same if you have been caught!
