This number showed up on the caller ID coming in on the line for a person that no longer works at my company. When I answered it, the caller asked for the CEO of my company. (I work at a medium-sized company, so anyone looking for the CEO that ends up in my lap either has no business talking to the CEO or is very, very lost.) The name associated with that number on the caller ID was "PRINCETON GRP I" - it only displays the first 15 characters on my phone.
I'd guess that the caller was from http://www.princetongroupsports.com/contact_us.html. I have no clue why they would be calling here as we aren't located in Chicago (or Madison or Atlanta).or
This number is in fact Princeton Group Sports Marketing (which has NOTHING to do with Princeton, by the way... they just stole the name). These people are [***] who try to jam you with phony sports tickets, etc. They also violate the do-not-call laws. If they are imposing on you with their BS, call them back on 312-781-6000 and ask for Marcus Davis. Give him hell.
