No Service / Breaking Contract

In the begging of the year (2022) I've canceled my Rain Home Unlimited WIFI because I was told by MTN they can give me better connection than Rain. So I've taken a 2yr R499 home wifi contact with them. It went good for a while but now for 2 months already I wish I've never done it... We can't watch Netflix without buffering, can't play playstation online because we don't have a good enough connection even to connect to a sever, don't even try to watch a 30sec YouTube video because you buffer so bad it takes you about 5min to try and watch, even trying to Google something is a impossible task without buffering ALL the time. And the best of this is only ONE device connected it even gets worst when connecting more than one device. Reporting to MTN is just as useless because all they say they are working in it and don't even offer any solution to the issue. MTN still charge me the full amount off the contract even though we can't even use their services. Dare you not paying for something you don't even have then they sue you for breaking contact BUT aren't MTN the one breaking contract for charging something we don't even have....?
