Who called from 7048972971

Just received a call from this number.  Caller ID showed N Carolina.  Since I don't know anyone in N Carolina I didn't bother answering.  Glad I didn't!  They didn't leave a message either.

Answered, but no one there. Sounded like a "boiler room" in the background.

Got a call from this number, no one answered me when I answered. Then they just hung up. Tried calling back and get a busy signal.

Hey Frank buddy. Plus, you didn't leave your phone number, which is a smart thing to do on a forum, but who would they know not to call back smart guy?

When I asked to be taken off this calling list, she replied, I sorry we can't.. then hung up on me.
