MetroFibre/VodacomFibre network

I am really taken for a ride here with Vodacom fibre. We have been having an issue with our internet for the past 4 months. Everytime they log a ticket with Metro Fibre and their team comes here and days there's nothing wrong on their side the issue is with Vodacom, when I call Vodacom the issue is with Metro fibre. So what am I supposed to do as a client? both my husband and I work fully remotely and we spent more money on the days that this network is down and we only get a credit of R50 from vodacom. I was on a long call with vodacom today and the manager told me the issue is Metro fibre. They called metro fibre and they came with some stupid excuse that my ticket is not closed, how is it my issue when the technician came here on Sunday and said there is nothing wrong as always. Honestly someone needs to take responssibility for this issues. And can I not get charged for wanting to cancel my contract to get another service provider that will assist me when I have an issue
