"The quickest way to resolve all of these billing shenanigans: file a consumer complaint with the FCC"

This , I had to do this with Comcast because of their craptastic service ,BS, and invalid billing. Trying to cancel them I kept being passed around to ALL the wrong people and departments, hung up on, refusal to give confirmation that the service was actually cancelled. Finally figured the only way they would cancel my service was to write a complaint to the FCC.

Sure enough just a few days later comcast called and apologized and cancelled my service as requested and fixed the hundreds of dollars of wrongful billing.
