Even if you go to Google's contact page now[1] it's obscure and the first thing they try to do is shuttle you off to forums or a boilerplate FAQ. You can't run a consumer business like that.
Google is great at building pure tech products like Google Search and Gmail, but not so good when it's a product where you might have to talk to a human being.
(I work at Google, but I had the same experience before I worked there). I think the best way of putting it is that (the consumer part of) maps is a library book, and that you wouldn't expect phone support for a library book. You would expect phone support for a product you buy, and you get that. (Google's service for pretty much all of their paid products is decent, or at least it exists). Did/does Microsoft offer phone support for their free software products? I just looked for help with outlook, and got directed to...a chatbot.
