Bad customer careSR2

We have been struggling to connect our fiber. Today a technician comes out fixes the internet connection (or so to say) it says now connected vut no internet we have been phoning the customer care number ***. No answer please note that we have been struggling with vodacom for the past month. After n month they come out to supposedly fix the problem now we sit with a new problem again. Honestly tired of vodacom they have a very bad customer care ( if there is one) like i said no answer
