Vodacom "LTE Interim Fibre Solution" not working

I have been having intermittent connection issues with my "LTE Interim Fibre Solution" that i signed up for in January 2019. Fibre was to be installed within 3-6 months, hence the "Interim Fibre Solution". There is still no Fibre on my street, though all the streets around have fibre. I have logged numerous Service Requests since the issue first issue arose around the middle of March 2020, Service Requests keep getting closed, but my issue remains. Router connects to internet, i run a speed test, 6Mbps Down, 356 Kbps Up, test again a few seconds later, 356Kbps Down and 100 Kbps UP, constantly disconnects from server every 10 minutes or so. Since signing up in January 2019 until mid March 2020, average internet speeds were, 30Mbps Down and 6Mbps Up. Which i was happy with, considering its only supposed to be an "Interim Solution". I am absolutely fed up, paying for a service that does not work as intended. So tired of speaking to call centre agents and not getting feedback, or fixing the issue. This is my last attempt at rectifying the issue with vodacom before engaging with my legal counsel.
