Impossible to cancel expired contracts or reverse unauthorised upgrades

I have been trying to cancel Vodacom contracts that have long since expired, and the process has been nothing short of impossible. Despite repeated attempts, I am met with delays, deflection, and no resolution. To make matters worse, upgrades have been processed on my account without my consent. When I returned the devices and requested the upgrades be cancelled, I hit the same wall — it appears to be virtually impossible to get Vodacom to reverse an upgrade, even one that was never authorised in the first place. This is not a once-off issue. It is a pattern of making it deliberately difficult for customers to exit contracts or correct errors that Vodacom themselves have made. Locking customers into services they did not agree to and then making cancellation nearly impossible is not acceptable business practice. Vodacom, I require the following: 1. Immediate cancellation of all expired contracts on my account. 2. Reversal of all unauthorised upgrades and confirmation that no further charges will be app****. 3. Written confirmation that these matters have been resolved. I should not have to fight this hard to cancel a service I no longer want or to reverse something I never agreed to.
