There's probably some other explanation. I wasn't under the impression Google employees can just go read your data like this. And if you want to believe imagine they can -- it'd be dumb of them to do it in this fashion. If you didn't leave your number on your emails/website/resumes/Facebook/etc. or given it out previously then maybe the employee got it from someone else who had your number.
Thank you for sharing your completely uninformed opinion, and asserting it as fact with literally no reason to think it's more correct than mine.
I in fact do have evidence to believe it's more correct than yours but I have no inclination to discuss it further.
