This number called me asking for my wife (by her maiden name).  Said he was trying to confirm that she had lived at a certain address.  Told him that we had only lived at our current address and not at the address the guy was giving.  He then asked for my wife's SS# and I told him I wasn't giving him any information.  When I got home that night, I told my wife about this and we have decided it was a scam or some type of fishing scheme.  My wife called the number back and the recording said it was "Gatestone".   Upon review of Gatestone - it seems to be a bogus debt collector trying to push people into paying for "debt" they don't owe with their threats and pressure.
