None service delivery

I signed a 24 month Fibre Contract with Vodacom in Feb 2023, since March 2023 I have intermittend internet issues monthly. I logged online service requests nd it just gets closed off with no solution to the problem. On 3 Jan 2024, this very same issue continued, i kept on logging service request on the Vodacom app and nothing happens, I eventually called Fibre customer care directly, they suddenly cannot pic up my queries logged untill I give them the service number. Now every night punctually between 5pm and 8h30pm my Fibre is 100% intermittend, I cannot use it at all. I logged a final call and warned them that I will cancel my contract due to no service delivery. I keep on following up, every call I make they only see a query logged for March 2023 untill I give them the latest reference number, then suddenly they can see my quey, still not resolved. I now want to cancel my service with them and they threathen me with cancelation fees, yet they have not been able to resolve any of my service requests since March 2023. I am now going to advertize on Vodacom social media my whole complaint and call out any layer who will be willing to take Vodacom on, this is just rediculous. I must just continue to wait and they do not care to sort out their service. i know I am 1 customer in a massive corporate compny so my money do not matter to them so why not just cancel my service so i can get someone who can actually provie a proper service and connection. They must think I am stupid, telling me they see one complaint untill I give them a ref number then they suddenly can see one more, really??
