Entering bank information when paying not going through

I can certainly look into why the system isn't accepting your payment details @am222t. To help me narrow down the issue and get this sorted out for you, could you tell me a few things?

Are you seeing a specific error code or message when you try to submit the information? 

Also, are you trying to enter this on the Xfinity app or through a web browser? If you are using a browser, sometimes trying a different one or clearing your cache can help the system process the details smoothly.
