LACK OF SERVICES PAID UP FRONT FOR

I paid the upfront fee of R479 the 28th May and Ricad the Sim. I was able to use the WiFi the 28th and 29th May. There after the WiFi stopped working. I contacted support on numerous occasions and logged plenty calls. Each time I was told the settings were incorrect, there after the router was blamed, changed the router as well as tried it in my phone still nothing. Was then told they will be connecting us to another tower still nothing. In all this time the network department never contacted me. I asked if the Sim was not faulty, the agent arranged for a Sim swop. Ram delivered the Sim today. It is now the 3rd June 20:35 and I still cannot use the service I have already paid for
