The way I see it, they are rude to you by making you go through hoops, so I am rude to them. I repeatedly say "Please cancel" to every new rep I am transferred to and/or every time they ask me a question or go into a spiel.

The only time I will not say "please cancel" is when they ask me any information that needs to be verified in order to cancel. This has worked with Comcast as well as a handful of other service providers that I wished to cancel. I have never been on the phone more than 6 minutes. Try it out.
