I get these about once per month at work; I've experienced the "break in" where a person "steps in" and clarifies something that's off-script. There doesn't seem to be a "take me off your list" response; they typically hang up immediately. What's interesting here is probably the growing data set that they -must- have by now. You could argue that Facebook's "M" is on the same spectrum of technology, leading toward a fully-automated voice response unit.
