I have extended basic cable - no box - just cable. Yesterday I lost a block of channels: 39-59. Everything else works (2-38 and 60-82). I called Comcast and they said I'm not paying for any channels above 35 and that someone must have realized the error and turned off the channels I'm not supposed to get. That doesn't make any sense to me. We've had these channels since we started with Comcast. And if someone did turn off the channels we are not supposed to have, why do I have 36-38 and 60-82?
