We understand how frustrating it is to suddenly see your card rejected or declined.
Our payment system can only accept US issued credit cards and not debit cards.
If you do have a US issued credit card and is still being rejected, there are a 2 things that you can try to do:
1. Clear cache on your browser and try again
2. Try on a different device / browser
In some cases, the bank issuer may also flag the attempt to charge your card and automatically reject it. You can call and check with your bank if they are blocking the payment.
Other cases are the expiration date section. We advise that you manually key in the expiration date along with the "/" symbol.
If you're still having issues, please send us screenshots of the error message that you get to firstname.lastname@example.org
