STOP CHARGING ME FOR A CANCELLED CONTRACT

Vodacom, please stop charging me for a phone contract I have CANCELLED. They called me for an upgrade, I asked them to cancel the contract and they agreed. I was then charged passed my contract expiry date for 5 months despite me telling them multiple times over multiple calls to cancel my contract and Vodacom agreeing to do so. My case was handed over to MBD (legal). I was forced to pay R2229 and told my account was settled and contact had been cancelled (June 2025). I went into Vodacom to inquire into a new contract today (December 2025) and got told I still owed an additional R2500 which had been billed up until August 2025 and handed over to MBD AGAIN!! This is theft and my credit score is now being affected due to vodacoms incompetence. I have been refused a new contract until this account has been settled. HOW MANY MORE TIMES MUST I CANCEL THIS CONTRACT BEFORE IT IS FINAL?? How much longer will I be charged for a contract that ended a year ago?? How can I be expected to continue paying for a service I am not receiving? It is enough now. Do not work with Vodacom.
