Having been an administrator for a Google business account in the past (and not a small one either) I can state from experience that if your problem doesn't have something to do with advertising or search, you are a distant (incredibly distant) third on Google's priorities. And search is a pretty distant second from advertising. Google is majority an ad company, that's what motivates them and it shows in their lackluster customer service for anything that isn't advertising.
Rely on them at your peril. They have slick products as long as they work but good luck if something goes sideways.
I have a G Suite account and GCP account that I barely spend, and I've always had an excellent experience with their support as long as they could solve the problem. The only time I grew frustrated had to do with Google Music and their support didn't have any answers or solutions at that time.
