I have received multiple calls that leave the same exact (prerecorded) message stating I need to call them at 866-*** about an "Unsecured credit debt" and gives me a reference number of 660005. The caller I.D. is showing 601-*** out of Mississippi.
I do not have any "Unsecured credit debt" therefore, I have not called them back.
I have checked my credit and there is no unusual activity.
