Google " rejection phone number" or some similar phase and get lots of ideas to stop unwanted calls.
for cell phones go to http://www.youmail.com/home/corp/feature.do?name=ditch and sign up, it's free.
Land lines, you can buy a phone for 50 to 60 dollars that will block up to 30 numbers ( it rings once and hangs up).
Seriously. This is WELL PAST the point of Harassment! EVERY DAY, yes LITERALLY EVERY DAY I receive calls from, (214) 506-7149, or (214) 506-7148. I wonder if they would like if WE called THEM incessantly, EVERY DAY. Multiple Times, EVERY DAY.
