Vodacom fiber is terrible

They installed my fiber about a month ago and since then they haven't put in my configuration settings, the call center you call with the number 082 190 4 has no real power and cant do anything to help me, the managers I've spoken too say they will call me back and never do or they lie to me and say my internet is working and when I get home nothings changed, if they could give me my config user name and password I could enter my own details into the router but they either wont or can't
