I saw this with Tivo recently too. They asked me if I knew anyone who wanted to take over my account because I apparently had a grandfathered $13/mo account rather than the current $15/mo rate. As if that made the device worth its weight in gold and it was my obligation to find a new home for it.
In the end, I just told the sales-lady that at the end of the call she will cancel my account. How long the call took was entirely up to her. Seemed to work, though I don't enjoy being rude like that.
