I've had Google call me 3 times this week asking what my business address is. I told them to do a Google search and find out for themselves.
I *wish* Google would call us and ask us what our business address is. Google Maps is convinced we're at Bronte St. S, rather than Bronte St N. The same thing happens to folks on the South side; it's not unusual for me to find a very confused driver parked in our lot.
More than likely a phishing scam of some sort. Most companies nowadays will either contact you via snail mail or email,
Are you sure it's really Google? I've never heard of Google manually tracking down information. I bet it's a scam or some sketchy marketing.
