Poor service, poor internet and refused cancellation quote

I took out a contract with Vodacom Fibre in August 2019. After a few weeks of use, the internet became unstable, and dozens of calls and service requests a few months later have still not resolved the issue. Multiple tickets on my name were just closed without any further communication from Vodacom.

After this constantly abysmal level of service, I called to find out what cancellation fees would be involved, the agent outright refused to tell me what the cancellation would cost, as he said that they could only quote me for the cancellation once I've officially given notice of cancellation - It is beyond ridiculous that they cannot even tell me how much it would cost to cancel the service.
