The number leads back to something called predicto.com. I called both predicto and heycosmo and told them they contacted an secure internal government mobile phone and they were kind of scared when i threatened legal action.
Recieved a call on my cell phone at 3:40PM EST from 302-336-7405. Picked up on second ring, no one there. My cell phone is also on the Do Not Call list.
They got me too. Called 12/19/2008 at 3:44 pm. I thought that entering my cell on the Do Not Call Registry would put an end to calls like this. Will be lodging complaint of coure. Reverse lookup on Yellowpages.com didn't tell me much....glad I read these posts before I actually called the number back.
