If your payment fails, it may be due to one of the following reasons:
Verify Payment Details:
Please confirm your credit card number, expiry date, and CVC, and retry.
3D Secure:
If you receive a 3D secure authentication code, it indicates your bank requires additional verification for your transaction. As this security measure is implemented by your bank, please contact them directly for assistance.
Card Declined:
If your card is declined by the bank, please contact your bank for further assistance.
Alternatively:
Please use a different card to complete your purchase.
