got the same thing today 1:22 pm  I do not answer unknown calls!  Now I see why!  I am on the DO  NOT CALL list also!

Got a call @ 1213 PM. No one on the other end when I answered, probably scouting for working numbers. Thanks for all the updates on this and thank you 800notes for this service.

i called the # back(406-478-2002),, a woman answered saying it was a canadian pharmacy..

I too just got a call... caller ID simply said "Montana" and the phone number.  I'm in Pennsylvania.  I did not answer and they did not leave a message. I'm also on the Do Not Call registry. More scammers & jerks!

I tried to call them back to have my number removed and it said "No longer in service."  That's the fastest discontinuing of service I've ever seen. How lucky was I to have been called before their service was lost! /sarcasm
Seriously, if I could reach through the phone and strangle these idiots, I would.  Then I'd wash my hands over and over.
