Missing channels on Xfinity

Hello,

I recently purchased a 185 channel premium subscription with

Xfinity in order to begin receiving the Marquee channel which  I believe is offered to the greater Chicago viewing area.  After obtaining Marquee I noticed that I had lost service for the TCM (Turner Classic Movie) channel, one of my favorites.  After making four phone calls to Xfinity customer service when each rep assured me that the channel would be restored within an hour.  One rep even offered to give me a free internet speed upgrade.  As of today, 1/21, nothing has been accomplished and I still don't have either Marquee or the upgraded internet speed.
