I got a call form this number today, June 11, 2013 at 9:32am. When I answered the call I heard silence so I hung up. I immediately got on my Google phone (as it cannot be traced) and called the number back, after two rings the call was answered but all I got was silence after saying "Hello" twice. This has all the ear-markings of a scam.
Just got a call a few minutes ago, was a number that I didn't recognize so didn't answer.
There ought to be a law. Oh wait, isn't there?? No teeth in it though; what an annoyance.
