Who called from 4842543815

this number continually calls my home and if I answer there is no one on the other end and if I don't answer no message left on answering machine.

I have received calls from this number for 2 weeks now.  Sometimes once a day, sometimes twice - could be in the morning or even 10:00 at night.  Every time they call I file a complaint with the National Do Not Call Registry, but nothing has been done.

Same as everyone above, but I did answer it tonight and it said some kind of code and disconnected - this is BS!  Any idea's of what to do - or what type of company this is?????

I keep getting calls from this number on my cell but no one is there when I pick up.
