Dynamic Recovery solutions Scam company trying to collect a bogus debt never incurred greenville South Carolina

Was contacted by this company by phone trying to get me to pay $3200 for a debt they said I owed Citi Financial. I never had any debts with this company so I told them it was a mistake.  Got a letter a few days later asking for me to submit the money by credit card. I called them and disputed the claim. Worried that this was identity thef I contacted my protection company. They never heard of this debt.  This company said my debt was written off in 2001 by Citi Financial and they just got the account.  Once a debt is written off they cannot come after me.  After 10 years they cannot come after me so I knew this ws a scam.  Googled this company and found all the other reports of the same scams.  Going to report them to the AG's office. They need to be stoppped.
