Canceling a Vodacom contract Mission Impossible

Canceling a contract with Vodacom is truly a Mission that is Impossible. After adhering to the 24 month contract, you have to call to end the contract otherwise it continues indefinitely but they say it's 24 months. After you cancel you'd think they'd move to prepaid since you've paid up everything, no. They put on another contract called "Flexi Zero" with network issues and no caller ID. After weeks of calling and holding I'm still on Flexi Zero with no caller ID, worst experience ever! I regret the day I walked into Vodacom
