If you don't owe any money to any debt collectors, then just tell Allied Interstate they have the wrong person and they will (by law) take you off of their calling list. I called them and asked who they were and before I could finish, they asked me if I was "Daniel." I told them, "No, my name is not Daniel." The operator took me off of their calling list. If you think you might owe some money, then you should do what Nelly suggested.
