This is a Internet scammer beware

I got a call and they said my name and I said no who is this and they hung up. They called back several times and I didn't answer. Had someone else call number on a prepaid phone and it says Magic Jack. Not going to answer and blocking the number.

who the hell is calling me?

In the last 24 hours, I've received 3 calls from this number.  There was one message on the last one, but it was just 5 seconds of air.  I tried calling them back to see if it was someone I knew, no answer.  Looked up the number and found this thread.
