A call on Tue., Jun 01, 2010.  
Caller ID= "Perfect Network" 406-530-5128
Oriental girl with VERY poor English skills wants to sell a power wheelchair to my mother.  She knew my mother already had Medicare BUT asked the card number.  At that point, I told her she was illegally telemarketing and she wanted my mothers' Medicare number and other identifying information.  
This appears to be way beyond a prank call.  Be VERY careful of these vermin.

PS: When I asked her which company she represented, she said she was 'with' Amica company.  Yet, the caller ID indicated 'Perfect Network'.

Received a call on my cell which is on a do not call list.  Couldn't understand person speaking well.  Appeared to be selling something.  Said that I wasn't interested and not to call again & hung up.

Got a call from them this afternoon and didn't pick up-- no message. Caller ID says "Perfect Network"

3rd call that I got within a week's period to my cell. The person will not speak...I tried to call back but the line was busy/disconnected. They only call in the late afternoon/early evening.
