I received a call from them on my cell last night at 9:15pm. My cell is registered with the DNC as is my other phones yet they still call.
Here's some info on who they are:
Marketing Source One
608 S. Washington Street, Suite 101
Naperville, IL 60540
(888) 676-6311
I found this out from a legitimate company they were calling on behalf of. When I filed a complaint with the BBB of the state the company was in, I received an immediate response from the owner who gave these clowns up to me in an effort to save her company's reputation (wise move). I filed a complaint with the AG's office of Illinois against these creeps.
Called this number back; their recording prompts you to press 1 to be removed from their calling list. If you go thru that exercise they'll prompt you thru some options to either leave a voice message or talk to a live operator. I've stayed on the line for several minutes but was never connected to a live operator. During this process there was at one point a message that said that if you would like to call them back to call 971-220-1984 which seems to go thru a simliar routine.
I'd pay $$ for someone to come up with a way to trip up these guys!!
