I know - because I am one of those humans in support grins. I work in the support organisation for GSuite (formerly Google Apps). And I work across the hall from the guys who support GCP (Google Cloud Platform). And there are an entire army of us, helping support many, many enterprise customers.
Even our consumer products have real people manning support phones - I know, because I've had to call them before (mostly Google Play Music issues - this was before I joined Google, so I couldn't use my internal pull...lol).
Regarding your second point - abuse is a real problem for any cloud provider. I know, because I happen to work in anti-abuse. It's a difficult problem to crack, and there's a lot of smart people (at many companies) trying to solve it. But please understand there are real humans at the other end, trying to provide a good service - and it's not very kind to take cheap shots at them.
There usually are appeal processes available for nearly any kind of action taken - if you were actually personally affected by an issue, or feel unsure about how something was handled - please feel free to reach out to me. I can't guarantee I can wave a magic wand and fix it, but I'm certainly willing to reach out to see what can be done.
