We have recently gotten numerous calls daily at my office. Yesterday we had 4 calls from this number. No one is on the line when we answer, and no message is ever left. Surprisingly, I just answered and there was a person on the other end of the call! It was someone from Google trying to get me to increase my office's visibility on the Google listings. I asked if they could stop calling me, and the person said yes and hung up on me. What an irritation!
