Have received several calls from this number, and many other unknown numbers, since I made insurance inquiries on the web. Obviously, one of the insurers sells their call lists. Wish I knew which one, so I could complain! I don't answer unfamiliar numbers, so good luck with that!
I looked up health insurance quotes for my son and someone called today to my cell phone from that number looking for him. They hung up when I asked who it was. I'm going to block them too.
