If your payment has failed this can be due to a number of reasons:
1 - You have exceeded the credit limit if the card you are using is a credit card
2 - Fraud prevention. Your card issuer has blocked the payment since they need authorization from your side to accept the transaction.
3 - There are insufficient funds on the card if the card you are using is a debit card.
In the first two cases, we recommend that you contact your bank in order to resolve the issue, this is usually a fast process and the bank can allow the transaction after a few security questions.
In the last case, you will simply need to add funds to the payment method or use a different payment method.
If your request has been accepted but the payment fails, we will send you an email with instructions on how to complete your payment.
