Good retort here on why CSRs do this:

But overnight my sympathies shifted: If you understand this call as a desperate interaction between two people, rather than a business transaction between a customer and a company, the pain is mutual. The customer service rep is trapped in an impossible position, in which any cancellation, even one he can't control, will reflect poorly on his performance. By the time news of this lost customer reaches his supervisor, it will be data—it will be the wrong data, and it will likely be factored into a score, or a record, that is either directly or indirectly tied to his compensation or continued employment. It's bad, very bad, for this rep to record a cancellation with no reason, or with a reason the script should theoretically be able to answer (the initial reasons given for canceling were evidently judged, by the script, as invalid). There are only a few boxes he can tick to start with, and even fewer that let him off the hook as a salesman living at the foot of a towering org chart. The rep had no choice but to try his hardest, to not give up, to make it so irritating and seemingly impossible to leave that Block might just give up and stay. The only thing he didn't account for was the possibility the call would be recorded. Now he's an internet sensation. The rep always loses.

Of course, it's absurd that a company like Comcast is able to force two humans into combat like this in the first place. If you don't take the existence of a near-monopoly company like Comcast for granted—and why should we?—the situation is as clear as can be: The rep didn't abuse Block, and Block didn't torture the rep. Comcast, the organization, is tormenting them both.

Comcast and Time Warner are in the process of merging in a paper-swap worth somewhere north of $40 billion. They are doing this to consolidate power, to consolidate assets, and to make the relationships like the one they once had with Block not just deep, but permanent. Comcast's call script could not account for the possibility that a customer might choose to switch to another company that isn't "number one," as the rep repeated, out of distaste. A merger might fix that: It brings these companies one step closer to making sure there's no number two.
