These guys are phishers/scammers. They are just trying to extract your information out of you. I have spoken to one of their representatives several times and asked to be removed from their list, pointing out that I am registered on the National Do Not Call list. This often results in them hanging up on me, or just patronizing me. They still call me every day. It is a complete mystery to me why the FBI hasn't shut them down.
