Comcast XFinity Lost service for 3 or more days at a time for no reason for years, then after snow storm of Christmas Eve 1012 lost service for 12 days, promised refund for time without service, Comcast reneged Little Rock, Arkansas

In the 11 years that I had Comcast for both TV and Internet, I counted 10 outages which seemed to be for no reason and which lasted for 3 or more days EACH and it was getting worse each year.  These outages were neighborhood wide.  In February 2012, I left Comcast XFinity's TV service in favor of DirecTV.  On December 24, 2012, Little Rock, AR was affected by a snow storm that knocked out power for 3 days.  After the power came back on, Comcast denied us service in our neighborhood until January 5, 2013 by which time I had had Exede come out to set me up with their Internet service and I had already turned the modem owned by Comcast back into Comcast and was assured by Comcast that I would not be charged for the service days from December 24, 2012 until I had turned in their modem to them on January 5, 2012 which meant I should have been charged for only 4 days during that particular billing statement which would have been for a cost of $6.57, they charged me for a total of 16 days (including the 12 days of nonservice) which resulted in a charge of $24.87.  I have been fighting to get this bill corrected ever since January 12, 2013.  To add insult to injury, Comcast turned my account to a collection agency in late January 2013 even though I had made it totally clear to Comcast in 3 letters that it was their error that was causing me not to pay the bill because I was waiting for them to make the promised adjustment to my bill (they had promised this adjustment to all of their affected customers in the affected publicly on TV and the radio!) before I made payment so that I would be assured that they would not try to come after me for any fraudulent amounts.
