I don't see why anyone would ever use Google anything for a business critical use. They seem allergic to providing customer support for anything other than advertising.
Entirely anecdotal, but we've been using Google Worksapce since it was called Google Apps and my experiences with their customer support have been fairly positive. At one point, I had a rep chat with me for about 45 minutes trying to figure out a bizarre problem, then we figured out that it was likely something outside of Google's control and instead of saying "we can't help with that", he setup a call about an hour later with an engineer and himself so we could verify. Turned out to be a DNS misconfiguration (a TXT record was double quoted from what I recall), but we struggled to figure that out and after a 30 minute call, we had it fixed and they emailed me a week later saying they had updated both internal and public support docs to include my edge case and had introduced a more descriptive error.
It's not the best support I've received in the IT sector (Linode has always been my favorite for that; I worry Akamai will ruin that though), but it was pretty close.
Sorry to go against the stream but I have to say that they do have customer support for some businesses. They wouldn’t be the third cloud provider without that.
To be fair, they do provide support including live chat if you have Google Workspace (previous called GSuite) subscription. There is no support if you are on free gmail.
I used to pay Google around $5/month for a single-user g suite business account.
As of a few years ago the support was surprisingly good. I could call even call them about issues outside the scope of g suite, like Google play store region setting bugs.
