Most Google users don’t pay a dime for their services. I don’t think it’s reasonable to mandate customer service for free users.
They’re not a charity. But they also don’t owe their users for what’s tendered for free.
Where I’d agree with OP is in requiring extensive CS for paying users.
Ban gmail addresses being used for government services, banking, health, utilities etc if they don't want to dip into the staggering profits they generate off these "free" users to guarantee basic rights and recourse from their own systems.

It's not for free, why do you keep repeating this line? Google isn't offering charitable good and services to people.
Nobody is forcing you to give things for free, so, you're responsible for those customers as much as you are for the paying ones.
And actually, it is not for free.
The only other large company that I have similar experiences with is our ISP (KPN in NL) who are also really easy to get hold off and very helpful (down to helping you hook up your own fiber equipment).
