These people call at least twice a week.  I always ask who is calling and it's a different answer each time.  Always tell me that so-n-so called them first and they are just returning his call.  I'm always polite when telling them "He said Thank You but he is not interested" that's when they become rude.  Then I just hang up.

Receive these calls every week.  They make it sound like they are just following up a conversation with our President.  Not true. Leave them holding then they hang up.

Yup, been going on for years.  Usually a different person who is mystified, just mystified that anyone from the group has called before. When I ask to put us on do not call list they get nasty. I hang up.
