FWIW, when I've been buying ads, Google not only has customer service, the customer service is damn good. I guess that's why it's called customer service.
Hardware support has also been amazing over the years, as far back as the original Nexus 7 (2012) to replacing a broken Nexus 5X in Ireland last year. Probably the best customer service I've encountered from any company that I can think of.
I've had a Google-branded phone since the original Nexus and I used to agree with you, but their support on the Pixel 2's extended warranty (which they offered because of early problems) has been a game of passing the buck with Verizon.
