Vodacom Fiber nightmare

I signed up for vodacom fibre service in January. I had to call them for 5 months before they came to install meanwhile they are deducting my bank account with R599 monthly. eventually they came to do the installation in July. The next month the fibre is no longer working, I call Vodacom to complain, they tell me its because my order was cancelled because it took long to be activated. Another fiber connector is sent to my place. September I call Vodacom because the fiber is not working, I am told that its because the account is cancelled. Mind you in August i got a double debit of R1200. Then the month of September I got a debit of more than R2200 from Vodacom. while their fiber is still not working. This month I called to cancel the whole thing because its not working out. I was under the impression that its month to month now I am told I signed a 24 months contract, I will have to pay for the remainder of the contract. Still i ask them to give me the amount payable to get out of the contract they are not assisting. I am unable to get fiber with another company because of vodacom. Their service is pathetic.
