Scam.
I'm a Google Trusted Photographer and Google Agency. As soon as I mention this, they hang up.
Google never calls unless you're expecting them, and when they do, it's a 650 area code.
Your Google business listing is FREE:

The called several times and never left a message. I called back, and it was a message asking if I'd like to be put on a do not call list for that number. I accepted.
It’s NEVER Google. Google will NEVER, EVER call you. See www.SEOscam.net
I have a little fun with these types of calls.
I have VOIPO, inexpensive, but it lets me block several ways. It doesn’t matter how you try to make them stop they won’t because they are Not in the USA and no way anyone can go after them.
So, since they won't stop, I just forward their number right back at them and in some cases it causes their system to go into a Loop. Cool.
