Vodacom Fibre installation - fail, fail, fail

I am having having a very frustrating experience with Vodacom Fibre . I placed an order for fibre in December and on 9th January 2019 a technician spent three hours installing SO181 ********** 68. Left me a shiny Nokia router, lights flashing but no data. Said he would speak to his boss on Monday and sort it. Since then (and they make sure you cannot contact them by email, or heaven help us, by cellphone) I have spent several hours on their fibre "helpline" ********** . At least 3 agents promised to send out technicians, seemingly unaware the installation had already been done. One tech type was very interested and sent me a link through which he photographed the router through my phone. That was that, though. Yesterday two different agents Friedland and Mieta both promised to call me back. Nothing. I have been a contract customer for 15 years with Vodacom, but it would appear they are right out of their depth with fibre. I'm trying the competition now.
