Comcast - service outage

It only took a month after the switch from Insight to Comcast before my service was cutoff. I setup automatic payment via the website, and they claimed I didn't pay my bill. According to the website, there was no balance for me to pay, and yet on the phone system I was told my service was disconnected (without warning) because I had not paid my bill. Does the left byte know what the right byte is doing at Comcast? I think not.
