1.) The calls are coming in from overseas. Which means they are NOT being made in U.S.
2.) They are being used illegally.
3.) All phone numbers, starting with "712-429" that they have called from, HAVE been reported to the FBI.
So just to let everyone know, after a week or so, you shouldn't have to worry about someone calling you off and on. :)
One of the FBI agents had actually called me, and asked me what phone number's the have called me from, I gave them 712-429-0255 and 712-429-0252.
But of course he had a list with many many other phone number's on it as well.
Received a call from this person telling me that I won something. Don't remember what it was since I hung up as soon as he said it. I knew it sounded fishy so didn't waste time on the line.
