Poor sevice from Vodacom and Vumatel

Amazing! My fibre internet problem has not been fully resolved after a week and two days. I received an SMS from Brian (AI?) from Vodacom stating that "Vodacom Fibre support and I are working on the fault. We have arranged for one of our field technicians to come out and take a look at your issue. Please expect them with the next 24 hours."

24 hour has have passed and nothing has happened!!! I called Vodacom who says the ticket has been closed as the fibre problem has been resolved. But it hasn't as the wifi doesn't work!
