No, outsourced call center with no escalation path doesn't qualify as support for anything but the most basic issues. Google 'support' means bitching on HN, getting upvoted, and having an engineer take notice and actually poke at it.

No, it signals that you are reliant on them. This means they can treat you as a second-class citizen from the free users! This recent issue happened to one of my clients (not anyone in this thread), https://support.google.com/voice/thread/3818693?hl=en . Note, paid users can't request a free Google Voice account, have to pay for the same thing on Cloud Voice now.
We had similar issues in the past where we couldn't delegate users from a Google Business panel inside our G Suite domain, we had to maintain personal GMail accounts to add business managers.
I've been a reseller of this shit, deeply regret it. When it works for our clients, it works fine. When it doesn't, we're just as screwed with getting support as anyone else. I switched my primary accounts to Fastmail and O365, and haven't looked back.
I've been meaning to migrate to Exchange/o365, it's in my backlog of projects that I'm procrastinating.
They use free users as beta testers and to see if ideas stick. They can't deploy those to actual customers.
I manage my company's G Suite account, and their support hasn't impressed me. We were initially unable to set up DKIM. The page to generate the DNS record kept returning a strange error code. I talked to support they were friendly and apologetic, but the issue took months to fix. Every time I followed up I was told they hadn't even heard back from the engineers, which gave me the impression that the support department doesn't have much pull in the organization.
Paying for GSuite doesn't eliminate any of the problems (they'll still ban you, spy on you, have relatively poor support, etc.) and many of the alternative services are simply better anyway.
