If you receive a message that your payment didn’t go through, please check your billing and personal information to confirm that the credit card number you entered is correct.

If all details are correct, please try paying via PayPal. Don't worry, you don't have to be a registered member of PayPal to use their services.
If you selected to use “3 interest-free instalments” and the order was declined, the pending charge placed on your payment card will be released within 24 hours. Depending on your financial institution, it might
take between 1 to 7 business days for this to reflect on your bank statement.
You can also use a different credit card or simply try processing the payment again a few hours after your initial attempt.
