Keep deducting money after my contract was cancelled

<p>My contract was about to , so I.decided not to continue with the contract. In November of 2016 I handed in the necessary paper work. They told me that there will only be one more deduction in December. At the end of January of this year they deducted off more money. After hours on the phone struggling to get through. I got told that Vodacom has decided to not cancel my contract but to carry in with it without my consent. Who gives Vodacom the right to make these decisions. Very disappointed. </p>
