Complaint Review: SAR & Associate

This number keeps calling me and leaving messages saying it is the Civil Division and that I need to contact them to avoid further action.  I also got a  letter in the mail from them.  I answered the phone once and they said they are with a debt collection service collecting on a payday loan that I have that is outstanding, which is completely false.  I was the victim of a ruthless scam involving payday loan several years ago and immediately identified that this was a scam.  They are still calling.
