If you've received a payment processing error don't worry, you won't be billed. You can try entering your payment details again by clicking the “Retry payment” button. Just please double-check your security code and card expiration date before clicking “Process my order now”.
If the problem happens again, contact our Support team via the "My orders and payments" contact form. Please include as much information as possible, including steps that you've taken so far and any errors received, but DO NOT include your card number or security code!
