Employment- Employment Scam. I received a call at my job from Advanced Financial Servicing trying to collect a debt. First, he did not identify why he was calling, just wanted me to verify my personal information such as my SSN. I have received this call many time. They are attempting to collect a debt for a payday loan they allege I failed to pay from Fast Cash. I have repeatedly asked these people to provide info regarding this debt because I have never heard of Fast Cash. They get hostile and try to imply that I am refusing to resolve the matter. I finally told them if they would not provide me information regarding this "alleged" debt, then file suit against me and I would get the information inside a courtroom. Then they hung up on me.
