For several years this company USIS Comercial Service, sometimes call DAC, provided wrong and false background history to employers about me, it is been a nightmare for me and my family, imagine having your employment applications turn down all the time because they are providing wrong personal history, USIS Comercial Service had my name on their records as an ex-convict for drug related problems, when in fact Ive been a perfect citizen all my life, never arrested or convicted of any felony or crimes. If you work in the transportation or trucking industries and you are constantly been turn down by companies, you better check your DAC REPORT, maybe USIS Comercial Service is the one to blame.
