We're sorry to hear that you're having difficulties with your purchase. Because payment errors could be caused by any number of steps in the payment process, they're often difficult to track down. Please see below for a list of possible solutions to a purchasing issue.
Purchases through Mojang may be international purchases for those outside of Europe. If a credit or debit card payment is not going through, you may want to contact your card company to ask about the status of the transaction.
If you received a message asking you to wait 48 hours before you try your purchase again, that is a security restriction when purchasing through Skrill, and Mojang cannot lift that restriction.
When purchasing through Skrill, certain customers using certain payment methods are sent a verification code. If that code does not arrive, please email Skrill at email@example.com. Be sure to send from the email used in the purchase, and include Minecraft in the subject line.
Paypal is not currently an option for purchasing a Minecraft gift code online. However, you can still purchase a Minecraft account using Paypal.
Due to US law, many or all prepaid debit cards purchased in the US will not work for Minecraft purchases through Skrill, as the company is located outside of the US.
Sometimes a payment is unsuccessful when an unsupported payment method is used.
Alternatively, prepaid cards are now available in many parts of the world.
