On 10/29/2015, a man called and would not give his name. He said that he was from legal claimant services and wanted to talk to the owner of the company, Greg Header. I was standing when the receptionist answered the phone. This man was very rude, loud and threatening. He insisted on speaking to the owner. When the receptionist asked him for his name and number, he yelled at her and asked her what type of company we were running. She was only doing her job. The telephone number is [protected]. When you try to call it back, you get a voice mail that has the business name omitted and it states, "is currently closed, please call back during normal business hours." I recognized the number as one that keeps coming into my personal telephone and I was instantly thinking that this guy found me at my workplace. I knew the voice as he has repeatedly threatened me on my home phone and my personal cell phone. This has got to stop. What can I do.
