Reporting to DNC is fairly useless since that relays to your state's attorney, most  of whom have no interest or are swayed by lobbyist groups..

Report them to the FTC:

Yes, received call on cell June 21, 2011. When I returned the call I got a VM saying I had reached the call center and to leave a message.

I have gotten called 7 times in the past two weeks by this number on my cell phone.  Same thing, when I called back it was SMG call messaging center.

I keep getting calls from this number everyday- no VM, hangs up if I pick up- how do I get it to stop

Me too I got this called whi is that??
