I received a letter from Comcast yesterday advising me that I was receiving certain channels for no charge that were not part of my Digital Economy plan. Comcast also indicated that the channels would be removed by March 15, 2013. A list of channels that are a part of my plan was provided but I cannot tell which channels are being removed. It must be channels I never watch. Has anyone else received such a letter? Do you know which channels are being removed?
