They are not easy to get to admit it, but the company is Local Lighthouse. They robo-call phone numbers to try and trick people in purchasing their local services. The person I talked to was in Costa Mesa, CA. The trick is that they make it sound like they are part of Google. At the end of the conversation when I confronted the sales rep, he told me that they bought my phone number from Google+. When I told him that I was going to post this online, he told me that he was going to post my personal phone number online.
Called about a Google Plus business. I am a part of two businesses, so I asked which one he was referring to, and asked which Google Plus account was tied to this phone number. I said, "This all sounds very strange." And he hung up on me.
