Called my cell and knew my name. Asked for a friend of mine by first and last name. She said her name was Krystal and that my friend put me down as a reference but didn't ask me any type of reference questions, nor did she state what company she works for. She asked for my friend's phone number but I refused to give her any personal info about him and I could tell that she was irritated by that and asked if I could give my friend the number that she called from. I'm guessing that the call might have something to do with collections but I don't know how they got my number.
