They call mostly on weekends. My neighbors have been getting the calls too. I have been ignoring calls for a few months because spent my weekends out of my house. But became determined to find the caller because I am not home when they call. So, I answered the call and played with their menu options. When I presses 1 to "get more information" the menu gave me an option to take my number off their list by pressing 3 and entering the number. I did that. Now I need to wait for 30 days to see if this works.
