Failing to cancel a paid up contract and failing to resolve this even after i contacted them

Hi, i called Vodacom on the 3rd of November asking that the Cellular Number : *** NKOSINGIPHILE JOZINA contract must be called wef 30 November 2020. Clearly my request has not been actioned because the contract for this number is still active and my account was debited in December 2020. I called Vodacom in early days of December asking that this get fixed before the debit order goes through, i was promised that the cancelation department personnel will get back to me with answers as why this has happened that my contract is still active after I have requested for it to be cancelled. I haven't received a call from anyone until to date 05/01/2021. I called yesterday date 04/01/2020, again i was promised that someone will call me yesterday and that hasn't happened until to date 05/01/2021. i am frustrated and i need answers from high management why i am treated unfairly as a customer (TCF).

Kind regards NKOSINGIPHILE JOZINA
