I do IT for a local government office, and they went with comcast years ago. 3 different internets, phones, and TVs. It was mostly ok, but seemed like whenever it rained or got windy the internet would go out. Super convenient, considering they are first responders.
This office also, due to being the government and so on, has multiple comcast invoices, and after all these years doesn't know WHICH invoice correlates to WHICH service.
Of course they called, and wouldn't you know, comcast not only has no idea which invoice goes where, actually REFUSES to provide any assistance with straightening things out.
Good thing this office is getting rid of the comcast and going with a local fiber provider.
