Vodacom not allowing me to cancel my contract

I'm not even going to say that vodacom is the worst and most greedy service provider there is because by reading the comments we can already see this.

I have cancelled my "Month" to "Month" contract a long time ago. I did not agree to Pay the settlement amount because their terms and conditions does not state how they charge the ONT installation (I was charged R1500 even though the installation took 5 min). After back and forth communication for a couple of months vodacom still deducted money from my account after changing the reference numbers AND THE AMOUNT I mean who does that!

Today i received an email saying that I did not comply and they did not receive a payment from me so they will close the ticket. I emailed them 2 months ago and they did not reply!! Twice! Now you ask me why i do not want to pay?? I forwarded the emails to a couple legal advisors that will now assist me in this because this is just outrageous.
