This company, which identifies itself by the name Dynamic Recovery Solutions, provides a 1-877-821-1657 number on messages they leave for you, though the number that appeared on my Albuquerque Caller ID was 505-492-0559. I called them protesting I didn't owe anyone any money- they had my name, address, phone number (obviously) social security number and date of birth. They claimed that I owed money on a debt that was incurred 22 years ago and settled 20 years ago, when I obtained work again. Watch out for these folks. They're all over the web as buying up OLD SETTLED DEBTS and trying to extort money for consumers under the threat of legal action, liens, and making adverse reports to consumer credit reporting agencies!
