Vodacom Fiber poor service levels!

I would like to express my disappointment with Vodacom Fiber service levels. My router is giving me problems for thr past 2 weeks and I have reported it everyday and escalated it. I have been told a manager and second line support will contact me but it has been 2 weeks later and no one has contacted me to resolve my problem. I work from home and need my internet connection to work via Lan cables and unfortunately I have tried everything and these Lan ports are not working. I need a resolution to my issue as it's costing me money as I'm using data now and paying for a fiber service that doesn't work...
