Sure, I don't disagree and it's silly/illegal when it happens, but this doesn't mean you can't protect yourself (sometimes without much more effort) to prevent damage or even just more effort. I think most people have spoken to a support agent who said they'd cancel a phone/broadband contract, or worse, had to do something slightly off script and then confirmed that the agreed XYZ would happen?

Regularly XYZ does not happen, or not exactly in the way you agreed. They cancel your broadband too late, or your internet starts a few weeks too late, etc. You can try to get compensation, or even sue, but some of the damage has already been done at that point. While this okay for temporarily overpaying broadband, this is probably not the case for a company's main production system, where the risk is very high. The company might not even survive to sue.
