I received a call from this number and just like everybody else, I knew it was a scam. I hung up on them. I am now going to the store and buying a whistle. The next time they call, I will answer and wait to hear a human's voice and then I'm going to blow this whistle as loud as I can. If they are from overseas, I don't think I can be prosecuted, but I definitely know that there will be one less phone ringing in my house.
