After 3 early morning calls, I finally answered, hoping that they will stop calling. I am also on the "Do not call list" and have an unlisted number. When I asked where they got my number, the lady said it was from a company that sells the info. I asked for the name of the company. She got her supervisor. The man said it was Natamark (?) out of Phoenix, Arizona. I asked him to spell Natamark. He said that he couldn't, but I could "google it" and said he would take me off of their list.
