This number calls me 4-5 a day. I ask them to remove my number from their list and after that I recieved two prank calls today from this number. Something to do with a law firm and diabetes lawsuit.

Same as Raul. They call and interrupt your evening, but hang up after you answer. I tried to call back, but it rang twice and hung up again.  caller ID states it was a "Doctor Disup".

I received a call from "Doctor Disup" according to caller ID.  I actually received numerous calls from them.  The # was different though. It was 715-598-4805.  Everytime I answer, no response, until now.  Someone asked for me by my first name only. When I asked who was calling, they didn't respond.  Extremely bothersome.  Whenever I try to call the # back, its always busy. Don't answer it, it is a waste fo time.

they call, but no one says anything, i here background talking,

They called claiming that they have a special promotion to lower my electricity cost.
