Complaint Review: Law and Investigation Department

First i received a call from an inspector mike watson saying that i was in possible trouble and i needed to contact him. He kept calling but because of his accent and the title inspector i ignored the messages because that is not a legal jardon in the US. But one day I went to work and my boss called me aside and told me that a kelly smith called from the Law Department and said i was being sued from a financial institution and told them if i didn't want to have a warrant served to call her. In my line of work this is very damaging and caused doubts in my employers eyes. I was livid. The next time she called she try to tell me that I had filed a fraudulent credit report and I told her i have never filed anything and then she said that a law suit against me was being issued from a bank. I don't owe any banks etc. So i hung up. Then she called my work again and got to my top boss and I told her I wanted her name, number and the company name and that here in the state of Arkansas we have a Fair Debt Act and it is illegal to call at someones place of work. She said she knows the law and i said evidently not what is the real name of her company and the web address and she got indignant and hung up. This company has caused me problems now at my place of employment and it has upset my family thinking we are in trouble. Stop these people please!
