This number keeps calling my cell phone repeatedly. When I answer, no one is there.

Called my cellphone 8 times in two hours.  I never answer calls I don't recognize.  The Do Not Call list in useless, so why file a complaint.  I turned the phone off, but when I turned it back on I had 2 more calls from them.  I blocked the number.  I hope it works!  If people would refuse to answer calls this sort of thing would become costly and useless to the scammers.   Funny how some people just have to satisfy their curiosity

multiple calls over multiple days, not a valid call back number, no one on the line when answered

they called 15 times 03/18/2014.Reported each call to do not call complaint. Today answered each one said nothing and waited till they disconnect after 5 calls have not called back yet, it has been 7 hours. Turn in each today too for all the good that does.

I have been receiving calls from this number for a couple of days now, I have no idea who it is when I tried to call back it says the number is out of order.  Any idea who it is that's calling?
