Picked up the phone only to hear air!
here's the interesting part... Called the number back twice on my cell phone. Was connected to jivy, crappy music for exactly 8 minutes, then a recording said "good bye" and I was disconnected!
Funny thing is... Within 5 minutes of after that I got a call from "Duke Energy" (704-691-0042) spoofed number, and they hung up!

FOLLOW UP from Nov. 2 when I received a call from a number in my exchange 864 306 4843

So.... When someone writes, " Don't answer the phone because they (meaning the pathetic scumbags) will know it is a working number and they will call you   f o r e v e r  so
DONT ANSWER THE PHONE!
