I had the same call a while back. Fortunately, I hardly get any of these scammer calls, but when I do I talk rather rapidly, and with authority, and say "How did you get this number? You should not have this number as it is a classified number! You are in serious trouble! What's your name...... and that is as far as I got before they disconnect. I have more to add to freak them out, like we are tracking you with our spy satellite, but they never stay on the line long enough!
