own up to your warranty and come do Work yourself

I recently moved from my old address to a new one just 2 km down the same road. Previously, I used a Nokia Router, but for the new installation, I received their new S90 Ultra router. From day one, the router repeatedly lost connectivity, causing dropped calls and disruptions during online meetings that required reconnecting multiple times each hour—sometimes as often as 2-6 times. Vodacom's response was a series of instructions and troubleshooting steps, but they failed to address the core issue. Who is responsible here? Who is the technician? After 8 years of reliable fiber service, I am now faced with this subpar support, which refuses to help without forcing me to do their initial work first. I have been a fiber user for over 10 years, and this is by far the worst support experience I have encountered.
