Vodacom shocking customer service

Recently my wifi Fibre went down for 12 days. After numerous calls and losts of wasted minutes it finally came back on. Yesterday I received a call from vidacom engineer stating he wanted to find out if the system was working and if he could trouble shoot the router. I advised him the system was working perfectly and nothing needed to be done. He then totally disregarded my request and sent a software update to the router anyway. This then cause the internet to go off again. I am.now being told I need to log another ticket and wait 48hours for it to be resolved when they caused the problem. Which now means I will have been a total of 14 days with full internet access.
