Caller (sounds like the same voice every time) asks for the owner. When I say they are out of the office, they ask for his mobile number. I then tell them that I am not permitted to give it out and he then says that he needs to speak with him immediately. He goes on to say that he as been working with the owner on a project, and is not in his office right now (background noise suggests he is calling from a call center) so he needs the owner's mobile number to reach him. After going through the same process every time, I generally hang up. Call multiple time a week, always the same person and the same excuses. When number is called it says it is "not a working number."
