Who called from 6475550149

Some scamming company about your license for your computer.  Lady with broken English reciting a script.  When I said I worked for the FBI, they hung up.

When I answered there was nobody there just dead silence with random shuffling noise in background, very unnerving !!

I didn't say anything when answering. They asked for me by my first name and either a recording or another person said, "This is ___, hello" using my first name. I immediately said that there was nobody here by that name and hung up. WATCH OUT!

oooooooh. asnwered (for fun)...heard noise and laughing...eventually someone asked for "mr arnold..." when i said wrong number the person said f*** you and hung up. oh pissed me off.

I did not recognize the area code and did not answer the phone on 8/20/2014.
