"[Comcast] cannot accept bank payments on [my] account"? For how long?

Hey everyone,

I have had an issue with billing for my Internet Service for quite some time, essentially leaving me forced to pay my bills by Credit Card. I have been told, by support staff, that the issue I have continuously experienced will resolve itself within five months...five months ago. After trying to enroll an ACH bank account again, assuming I can now, I am facing the same issue today, where I am told, by an automated message, only that

and *only* allowed to "Save" details I never provided, so I wonder: has anyone had this issue with billing, and how did you resolve it if so?
