There must be a business opportunity here. Connect people who hate dealing with this stuff to people like you who love being an asshole. They get their service canceled without dealing with crap on the phone, you get to play the bad guy, everybody wins.
Its called being a lawyer. Its more about form letters sent via registered mail and filing legal injunctions than talking on the phone.
A decade or so ago, I came within days of needing one merely to disconnect a DSL line.
Once the cost of fighting the collections agency and the cost of the hit to your credit record exceed the minimal cost of hiring the lawyer, its a pretty obvious move.
Not kidding around at all, although its probably a better topic for a law blog than HN.
The main problem they're likely to have is authentication. Helping people is fun. Helping people who like having fun by disconnecting other people (-ex's, etc) is a problem and you need to authenticate them cheaply.
