They call my office repeatedly and when I called them to tell them to stop I was disconnected. A minute later I get a call someone saying they "noticed I wanted to improve my education" when i questioned the woman about who they are and then she hung up on me.
I stopped this by purchasing magic jack phone system. Acting as if I were interested and telling the company I was moving or this wasn't the best number to reach me and they could reach me at the new number (the magic jack number). I have cut down on telemarketer calls 90%. I don't even have a phone hooked up to the magic jack number. When I check to clear the messages, sometime there are more than than 200 calls in a week! I only use this number for annoyance calls.
