Failure to cancel a cellphone contract

I have been a loyal customer with MTN for over a decade. Recently in January 2026 my cellphone contract came to an end and I had decide i won’t be renewing it. Their policy requires that you inform MTN 30days before the contract comes to an end that you won’t be renewing it. I have tried numerous times starting from December 2025 via phone calls to their call centre, even went into one of their stores and have sent multiple emails to customer care, retentions and even customer complaints asking them to cancel my contract and to date the haven’t done it and failed to do it something about their own system not allowing it and the matter was escalated but still nothing. Ultimately they are still debiting my account for a contract that I requested be cancelled. This poor service has left me to never want to get any contracts in the future with MTN. Vodacom it will be going forward.
