Comcast is taking away my Business Class channels because they can't locate the package.

I have been a Business Class internet subscriber for 6 years. A little over a year ago, Comcast took over for Time Warner in Memphis.
They are running commercials on TV for "Business Class Internet with 23 cable channels while you work from home."
I signed up for this and recently transferred my services to a new local location. During the transfer, 1 of my channels became fuzzy. When I called to ask for a repair, I was told “you should consider yourself lucky to be getting free cable, you have no right to complain.”
One minute I’m thinking I will have my channel cleared up, then next I’m fighting to keep a package I’ve rightfully subscribed to and Comcast STILL advertises.
I’ve spoken to 5 people. None of them will own the issue. Some will say “We offer the package, but not for home businesses.” Other say “we never had such a thing.”
All act as if they could care less that I am a loyal subscriber. Comcast knows they have no competition and subscriptions are up during the recession because people are staying home.
What I want is, my 1 channel cleared up. I want to continue subscribing to the package I’ve always paid for and continue to get support when I need it. Not to be told that I’m getting something for free and to stop complaining.
