A payment attempt can be declined due to one of the following reasons, depending on the payment method.
The payment was refused by your Bank
It is possible that your Bank may be blocking the payment attempt. We suggest you contact your Bank directly in order to know the exact reason (for example, limit of online purchases for your credit card, insufficient funds, credit card expiration, etc.)
If you have reached the limit of online purchase attempts for a specific time interval, you may need to wait some time in order to make another purchase.
Wrong Payment Data
Be sure to enter the proper details during the purchase process (credit card number, expiration date, CVV/CVC code).
When you check your bank account or card statement, you may see pending payment authorizations. These authorizations happen in order to make sure the card is valid, and to check that you have enough funds in your account to make the purchase.
Any pending or preauthorized charges on the credit/debit card account will return to your account. Please note the amount of time it takes for the payments to return to your bank account is entirely dependent upon your credit/debit card company or financial institution.
Should you see a pending authorisation after 14 business days, contact your Bank for more information.
