I can call Verizon or Comcast right now and get someone on the line in minutes. Usually they can solve my problem too. Get Google on the phone though. (Amazon actually does deserve credit here, their customer service isn't the worst, by any means. But they have a litany of other issues, like a work environment where people have to pee in bottles to make quotas...)
I'm not sure there are any companies where you don't pay them anything and they have easily accessible phone support. Do you happen to know of an example? I never had any trouble getting support from Google when I was a Fi customer. On the other hand, I'll bet I couldn't get support for web search over the phone for love nor money. Similarly, I doubt I can call up Facebook or Twitter's customer support lines, although perhaps I am wrong.

They're still getting paid for your services. If my ad attention is equal to dollars, why don't I also get customer service for it?
I'd argue the idea that you shouldn't pay for services, and that you shouldn't expect to get customer support, are both examples of failures of the current antitrust regime.
Phone support is, unfortunately, a hard to find commodity anywhere in tech these days. Generally I have only selected web hosts and domain registrars that have 24/7, US-based customer service. I used to have a few options, now there's very few. :/ You're lucky if they have a ticket system they respond to in less than a day.
Even Metro has quick 24/7 phone support. Which, given the sad state of their online self-service options, has been the only thing that's kept me with them as long as I have.
