Asked to talk to the boss - about (generic description of our company) - when I asked what company he was from he said CBS.  I could have been mistaken - caller ID said GPS.  When I asked him for a number to call back he said NO THANK YOU and hung up.

Called and asked for the owners (husband and wife) by first names.  When our receptionist said neither was available, he said he would call their personal cell phones and hung up. Moments later he called my personal cell phone (I work here but am not one of the owners),  How he got my number I will never know, but he refuses to identify himself and his purpose for calling. He must be either a salesman trying to pitch something or someone phishing for information.

Called and asked for a guy at our company that has since retired.  Asked to speak to my boss I said he was not in and I would take a message and have someone get back to him.  He yelled at me and said he would not do business with us and hung up.  Tried to call the number back and no answer it just kept ringing.

Same scenario I have to answer certain calls - this happens to be a 360 area code and one of our facilities is in that area code.  He instructed me to tell the Owner that Tom was on the line.  He is still on the line as I type this.  Hope he enjoys our Hold music

This caller called several times.  If one calls back, you'll received a generic answering service.  The company name is austencibly "Global Profit Solutions" GPS, out of Deerfield, Illinois.  No record found for this company, no web presence.  Caller's name given is Mike Davis.
