The bank declined the charge with a "Do not honor" code or something similar. Please reach out to your bank for more information.
This can happen when a new credit card is used. Our credit card vendor will send out two charges, of which the first is an authorization charge to validate the credit card (this charge will be refunded or fall off in 5-7 business days). The second is the actual charge for the services being purchased. Some customers will see both on their credit card immediately, which is the likely reason for the error (the bank probably didn't accept the authorization charge).
