Yes, and I think it's an important example of "reason number three" that while cable television operators are subject to public utility regulation in most states they are not subject to nearly as stringent quality-of-service requirements as the telephone operators. You can complain to your PRC or equivalent body about nearly any interruption of telephone service, but when it comes to your cable you're largely on your own.
In my experience in New York, Verizon basically uses the public service commission as a level-1 helpdesk -- they take referrals incredibly seriously. I had an issue with Verizon equipment infested with bees -- and they literally rolled trucks within 30 minutes of getting a referral from the regulator, a pole and a bunch of equipment was replaced within 24 hours.
With TWC/Spectrum, unless they do something grossly incompetent or unsafe, the regulator is more like another party nagging them.
