Vodacom in breach of contract but cites contract back to me when I try to cancel

Vodacom promised me a 200/200 line for R899. They then messed up the switch over date, which left my household with multiple people working from home without internet for days. Then when service did finally activate, my own router would not work. I should’ve been asked when signing up if I needed the Vodacom router or had my own. So I was shipped a router I do not need, blocked from using my own router, which is better in every way. That was a hassle to sort out. Eventually I got someone who could help me get set up with mine. Then there are the speed issues. As I said in the first line, I was sold 200/200. Actual speeds are closer to 50/50. When I called about this, they said they see I’m down for a 100/100 and will resolve it. So firstly, they have the incorrect speed listed for me and then I’m still only getting half of that. So a quarter of what I was sold. All attempts to have the speed issues resolved have failed and the ping is outrageous as well. Now when I want to cancel, they first beg for another chance to escalate the issue and then have the nerve to try and charge me early cancellation fees. I have been paying for 4 times the speed I have been receiving, so actually Vodacom should refund me 75% of each payment I have made but I’ll settle for cancellation at no cost. If you need the router back to make that happen, you can send someone to collect it. After sending a mail of effect to support they simple responded at that cancelling a month to month contract within 12 months will have penalties. What then is a the point of month to month. This is disgusting. Giving this company anymore money is simply not an option. I cannot believe that after not fulfilling there contractual obligation, they have the audacity to quote the contract back to me. The only accepted solution here is to waive cancellation penalties

Support just insists that because the router, which again I say I did not need nor ask for, has been used so it has to be paid for. There is no way that piece of **** worth R1300
