Yes, they do have customer service and I did get on the phone with someone. I'm not sure if this is universal, or because I had a paid tier Google account.

That said, the rep failed to provide any definitive guidance on issue or resolution.

Good to know, thanks.

For Google Workspace (previously called GSuite), you do get support. Anecdotal but I recently used their live chat and the person was very helpful and helped me figure out a weird issue with a lot of patience. I would say it was a pleasant experience but this was the only time I needed them so far so you never know :)

I've also reached reasonable-quality support due to being a paid consumer of GoogleOne, which includes phone support for most (all?) google consumer products.

I even had them call me within an hour of opening a ticket.
