Thanks for getting in touch!
If you are trying to pay for an e-card as a gift for someone, be sure to visit this website. You could try it in an incognito browsing session. Usually does the trick 🙂
If not, take a look at this page where we go over all the scenarios why a payment is not going through.
Hope it will work. Let us know if there is anything else that we can do for you.
Have a nice day!
