They do have customer service, if you pay for their premium service Google One. They also have support agents for YouTube creators above a certain subscriber threshold.
For reasons I cannot fully remember my voicemail broke many years ago. It goes something like: I’d switched to google voice for vm, where T-Mobile handled my line generally. Then google did something to google voice, some sort of discontinuation + merging with gmail and my vm broke. This occurred in tandem with me moving to a house with terrible cell reception and before wide spread WiFi calling support. The result was that many folks figured I’d had my number disconnected because calls which couldn’t connect to my phone would get the “disconnected number tone” when being directed to my voicemail box.
Every month or two I’d fill in the google support text area explaining the problem. No response for ~4 years. Just this Feb, for whatever reason, I decided to call T-Mobile and report it. Problem was fixed by a higher up tech that described the problem as “very strange” and the “first time” he’d seen something like this. It took approx. an hour.
Upon rumination I full accept that I took the “easy way out” by filling in the text box vs trying to talk to someone. End result is that google lost a gvoice customer and no one calls me anymore. meh
At least in the Chicago area, they seem to really prefer to speak on the phone. I'm hard of hearing so phone conversations are challenging at best and despite that, when I've actually been looking for work and talked with recruiters, if they do e-mail it's to ask me to call them. It's seriously annoying. I think a lot of recruiters here have managers who take the view that if they're not on the phone they're not "working."
Recruiters call me a lot in the UK. I assume it's because they're able to command your attention as long as you stay on the line. Emails are easily ignored.
