Derek @ Atlas Contractors Harassing Rude Calls Tempe Arizona

Some a**hole named Derek from Atlas Contractors keeps calling my place of business and asking for the owner of the business, the first time he called He acted like he was a customer or friend and I asked "Who is this?", he said "A friend", and I asked "From where?" He said "Tempe" So I said "I don't have any friends in Tempe" and then he says he is from Atlas Contractors. I say I have never heard of him. And he says he wants to know who my partners in business are and what there cell phone number's are and that they are expecting his call and I would be smart to comply with his requests. Well the fool doesn't know it is a family business owned by my brother and myself. At that time I told him I would not give cell phone numbers of anyone to someone I didnt know, but I would take a message for him. He then proceeded to tell me I was a tiger and growl into the phone and tell me I was probably a great f**k in bed and asked if I wanted him to come f**k me??So I obviously,I hung up on him.

This was not the first call from Mr Derek the a**hole and it wasn't the last. He just called again today and when I answered he asked for my partners cell phone number when I asked who was calling he said Derek, I asked which company he was with and he said Atlas Contractors and then I said "Yes I know who you are and no one here wants to talk to you and please don"t call here again" and I hung up. He then called backed and he hung up on me. This idiot thinks people don't remember his voice?? I am sure he will call again. What can be done about these kinds of harassing phone calls??
