This is a discussion forum where one can report or describe suspicious or unknown phone calls, but reporting them here does not stop the calling. YOU have to take action to do that! (google is your friend). Consider buying a call blocker from your favorite store if nothing else works.
I signed up at a work at home website and now I get at least 2-3 calls a day from different parts of the country. I keep telling them to remove my name from their list but they still call. So every time I block that number. The next day I get a call from a different city....block.....etc. Goes on and on. Maybe one of these days they'll stop.
