Sick and Tired of Drug Dealing in Public

Hi , Hopefully something can be done , I am tryingto bust drug dealing in Benoni , but when phoning SAPS they dont come out to the Druggies to bust them red handed , I have pic of dealing going down , here everyday , but no one seems todo anything about it .. Must I go out side and deal with him myself and have SAPS responsible or what should I do ? Maybe buy from him ? This is really urgent because our corner is being used everyday for drug dealing . Can someone respond to this urgent ? Thank you ..
