Complaint-Contract Cancellation Request not honoured by Vodacom and expected to pay

I have called Vodacom numerous times requesting for a contract cancellation. I have been sent from pillar to post- and now I am informed that I have to pay for a contract renewal that I never requested as well as cover the incurred cancellation costs. This is unfair and irregular and request immediate assistance and intervention as well as payment for the ******** debit orders taken from my account past two months
