There is a guy that keeps calling my work and asking to speak to me about a debt. I called him back and told him not to call my work and then he became verbally hostile and very unprofessional. I asked for his address and he refused to give it to me. I asked for a direct line to him and he told me he would be the one asking questions and said if I did not settle the account he would go to the Sheriff and have them serve me with papers. The only thing I have is his name, an 800 number, and the letters of his company. Can anyone help me with this please? I am also looking to possibly retain and/or pay an attorney here to even help send a letter to this person telling them to stop calling me.
