This person gave my several names one is Steven Smith, then Peter Johnson. They said they worked for the federal criminal investigations and received a file against me. They knew my social security # and address where I live. Then I received a call from a 646-918-0991 number same voice I thought I would be polite and listen to him once I requested that the information they had be sent to me in a certified letter the caller put me on hold and another man started talking to me. I repeated the same thing to him and I also made him aware that I had investigated the numbers and found them to be part of a scam, he got really mad, and threaten to come to my house. He even got my address. I told him to have a good day he told me "dont tell him to have a good day" he was really mad because I wanted them to send certified mail to me. I need to know how to put a stop to the calls?
