Nothing is harder than cancelling internet service, with the possible exception of cancelling a gym membership.
In order to cancel Mediacom's 'service,' I had to send a letter[1] to them, with copies to their general counsel, threatening 99 kinds of lawsuit. I made the letter intentionally deranged, complete with footnotes about financial BDSM, to give them the impression that I would actually do it. They cancelled the account. It was pretty fun to ignore the panicked calls from their lawyers for a bit too.
Once I had to cancel an entire credit card to get out from under a gym membership.
