Caller said they were from Google Maps and wanting to verify info people see when they search for my business. I saw no harm or risks in their questions. They didn't ask anything personal and didn't ask about anything that wasn't already available on the web. I asked them what company name and what phone number they have on file--everything was correct so I was satisfied it really was a call on behalf of Google Maps and it wasn't a robo-dialler call which would not have that info. So I went ahead and confirmed my address and answered her question about whether I provide services locally or nationally. Good for me in terms of marketing and free.
