Sometimes, banks and payment brokers flag transactions to our payment provider as fraudulent.
In our experience, virtual or prepaid credit cards often are the cause of problems.
If you are receiving the error message "payment refused", this is likely a result of this issue, and we can only advise that you get in touch with your bank and instruct them to unblock the payment.
If you accidentally purchase surplus packs, please refrain from redeeming any of the keys to your account, and email email@example.com immediately to ask that the surplus purchases be refunded. Please do not start playing the game, and then contact us, as our terms and conditions state that we cannot refund keys for an account which has logged play time in the game.
