Also, realistically, I don't imagine the phone number literally just telling you that the service wasn't available and hanging up. I imagine it would offer you options to get various pieces of information (the URL of the website, the legal address of Meta, how to navigate to the support knowledge base on the website, ...) and let you draw your own conclusion about how useful it was. Maybe it's occasionally handy to someone. At worst it's harmless.

I think in an ideal world, you could use speech recognition to let people leave a message, and open a ticket, as if they had emailed support@. When someone responds, the system gives them a call them back and delivers it using text to speech.
