It should not be a surprise that national "government" doesn't listen to the DA. It hardly listens to anyone as the ANC "government" is almost solely there to enrich themselves (there are some pockets of simple incompetence or following mad ideology).  The debacles at SAA, Eskom, DWS (Water), SANRAL, SABC, many municipalities and provinces etc etc are not really due to poor management. They are caused by extensive and institutionalized corruption from cadre deployment to tender rigging.
