department of law investigation adam said there is a law suite pending with my ssn number, cursed my supervisor, dispatcher and myself dallas, Texas

Adam called my job and talked with one of the dispatchers about me, dispatcher informed him that we do not accept personal calls at work. Adam started cursing at him. dispatcher said if he,s going to use that kind of language he would have to call the DA,s office. My supervisor came in and took the call, she wrote the name and number downon a sticky note and gave it to me. Before I calledI looked them up on the web and found out it is a scam . I called Adam from another phone and he asked for a number I could be reached at. I told him I,m not giving him my personal number. Thats when he said (look here you motherf*ker) at that point I hung up the phone. I called back when I got home and found out he had called and left a message on my voice mail. I saved the message and also did a reverse lookup of the phone number and found out that he,s not in red oak as I was told. He,s here in dallas in an apartment between dallas and mesquite. Don,t know where exactly but I,m still looking. Phone carrier is Caprock Telecommunications
