I have changed the payment method that was attached to your cart and attached the new payment method (the old card was declining because it expired in December). You should be able to submit the order now.
That's weird. There were three displayed cards with the same ending with 0075 and this one was with 12/20, which would correct, as it was renewed and submitted again, same number, just prolonged duration. On the other hand there are now two expired cards on display with 12/14 duration. I only had one back then, so one of them should have been 12/17 and the one with attempted payment should have been 12/20.
Well, it's working again, so probably no need to dig in to it anymore.
I've tried to place an order and my card has been declined for insufficient funds (correctly so far), so I tried to change the payment method to another card, but the system seems to be stuck in declined status of the original card (it keeps displaying the original declined message even after payment method change to a different card with enough funds). Can you please reset my orders so I can purchase again?
