Constant issues with Fibre

I've been logging the same query with Vodacom since May 2020 that there's a problem with the the speed of the fibre. Every ticket I've logged with Vodacom is for the same thing! Vodacom's response to this is to phone me, ask for 3 screenshots of the speed test 10min apart to be emailed but 10min after the email they simply close the ticket!!! Nothing is resolved except that I have to reboot the rooter every 2nd day!!!! i'm not surprised that Vodacom is falling apart - If my Managers were in meetings the entire day and cannot return a customers call, then I can see why nobody has any clue what is going on, how to resolve issues or even recover their reputation. If Vodacom cannot resolve their issues and provide the service they so claimed they are providing then I will have to see that this contract is cancelled at their expense, as they cannot provide the service stated in the contract making it VOIDABLE.
