The online bill payment does not correctly charge what is owed for the month. When you pay this amount, comcast will charge you a late fee for not submitting the correct payment.
According to the worthless customer service rep, we should be tracking our own movie rentals and adding those fees to the bill if we want it to be correct. This is a BILLION dollar company that can't update their online bill service to be reflective of what you actually owe?! How is it that I can receive a paper bill which lists one cost ($261), an online bill that lists another cost ($247), and phone service which lists another cost ($290) all for the same exact service?
This is stealing from the customer!
