Caller asked for Kelly, the home owner of such and such address, (assuming Kelly is a girl and I'm a guy) I said 'No I am not Kelly and no I do not live at that address' He then said, 'ok I'll call back later' and he hung up immediately. I then called the number back twice. The first time said the number is no longer a working number. The second time it said all circuits are busy and try again later.
I added this number to my 'Do Not Answer' list.
