Check out "I know an *** at Comcast" on facebook and become a friend. Yesterday's pleasurable experience with Comcast took 3 calls (one ended in being routed to a dead line that cut me off) and several hours as they explained to me that I signed up for premium channels (that I never signed up for) and how this was my fault.
Threatened them with the FCC, BBB and lawsuit. They finally corrected their mistake...after 3 hours on the phone.
Also, be careful if you THINK you have blocked a pubic listing of your phone number and address. They charged me monthly for "non-publication" and I did not know that they actually published my information.
Of course, no money reimbursed for that. Idiots!
