Some scumbag from OCG Publication group trying to sell Tradeshow publications

Obsessive calls, several times a day, leaves no messages in my voicemail so that I can call him back and tell him to stop calling!

They also use 520-917-0687.  He said he was with convenience store publications and I told politely we were not interested, so he decided to call and hit a different extension which I caught and proceeded to chew him out.
