WOW! What a complete JERK !
First  off, sounded like he was stoned out of his head, couldn't remember who he was calling for etc.
Then said he needed the head of maintenance. I advised him we have no such person and the jerk replied
" He JUST called HERE from THIS NUMBER !"
I replied "No, that's not possible nor true" and the jerk hung up on me.
Even if we had need of what ever this guy was selling, no way would we do business with such an unprofessional person.

Yes, this wierdo called our company as well asking for the maintenance guy (says he couldn't remember his name).  When we asked for the name of the company he worked for he just said "Contractor".  When asked to repeat he said "Contractor [***]!).  When the receptionist refused to give him the maintenance guys name and asked for him to leave a message with her he demanded to be put through to voicemail.  When she denied him he started cussing and calling her names.  

This guy is retarded.  Obvioulsy he's trying to pull some kind of scam but is too stupid to realize that if you start cussing and calling people horrible names and such, they are not going to speak to you.  This guy should be tracked down and jailed.

Just got a call from this number from "CHUCK" with " Maintenance Supplies". Wanted to give me some kind of gift card. Told him I could not accept as it was against my company's policy. That's when he put me on hold then shortly after that we were disconnected.
