Why was my payment card being declined?
Here are the most possible reasons:
1）Your card issuer might be having technical issues that prevent us from requesting authorization on your card.
2）Your card issuer might block the payment for security reasons, as it doesn't fit your regular spending pattern.
3）Your card is not activated for online payments. There could be a sending limit on your card that has been exceeded.
4）The network you are using to make the payment is not secure or unstable.
To help you make a payment successfully, you may want to try the following:
1) Using a different card to make your payment again.
2) Try using PayPal Express Checkout and choose a credit card. A PayPal account is not required but should help with processing the order.
3) Contact your card issuer to check if your card is valid, and can be used to make online payments, or if there is any recent technical issue or restriction on your card.
