I was wondering if someone can help me with what to do. Recently, someone - I don't know who - started calling my sister, who lives in a different state, about money they claim I owe. The number they told her to give me was 1-800-235-4153 extension 1277. Last night, my sister left a rather hysterical message on my answering machine demanding to know what is going on. They are telling her that it's about a lawsuit. To my knowledge, I'm not involved in a lawsuit.
