That is their same MO they scare you. They threaten you. They call names and get loud. When you ask for a physical location or a debt validation letter you will never get it!!
What has happened is they have purchased your personal private information. The original debtor sold it to them more than likely. They make calls to scam and they such you dry if you give them your checking account number!! So do not!!!! Also they work with Money Pak and Green dot corp. Money pal will claim that they have fine print on the back of their card and they will not identify the crook you paid. They support this activity and cover for them.
DO YOU WORK FOR THESE THIEVES? Because it kind of sounds like you do. Anyone with any knowledge of the law in this COUNTRY knows that any legal action against you needs to be in WRITTEN form. Random phone calls do no tcut it. Sorry loser!!!
Received a call from these folks, called back to see who they are the Lady said she worked for Recovery State Solutions but hung up on me when I ask her what they did. This is scam beware and don't give them any information.
