Hey there! We hate to hear that and want to help you figure out your payment problems. Just to cover some bases, have you been able to purchase other online items with your card? How about your network, is it solid and stable? Have you reached out to your financial institution to make sure everything is okay? If the answer to all of those is yes then submit a ticket with us so we can look further into this.
