Who called from 6072172810

When i called the number back says National Recovery put in your four digit pin?

I also just got a hang-up from 607-217-2810. When I answered there was an immediate click.

Upon researching the number, I found this:

"Prefer Not To Give  reported Unknown Drug Rehab In Binghamton from 607-217-2810 as a Prank Caller
Sep 4th 2009 - 10:58:59am EDT calling looking for a guy named Louis Gershon known to be drug user."

...I don't associate with the drug scene, so the caller must have either randomly dialed or mis-dialed my home.

2nd call to my cell phone with no pickup by me.  Don't know originator of call.

called no pick up at this end or voicemail

no message, a click when I call back
