I received a letter from them to saying that I owed the State of Maryland for back taxes. I never worked in MD so I thought something was fishy. There was no personal information on the debt request bill which was very suspicious especially in regards to taxes due to State Government. I contacted the Comptroller of MD and they had no information on due taxes. As stated by ibebozen, the State of MD does not hire out for collections. I received a second letter from them for collection after I requested a certified validation of debt, which they failed to fullfil and that put them in violation of the FDCPA. I sent them a response mentioning the violation, that I contacted the comptroller or MD, that I reported their violation to the FTC, BBB, and attorney generals and ACA international, and made sure to mention that if this was an attempt to a fraud, all documentation will be forwarded from the Attorney General's office to the FBI. Strangly, I have never heard back from them. By all means, they are a legitimately registered collection agency, but if they are fraudulent or breaking the law, please people report them to the proper agencies!
