Vodacom Contract Cancelation

Vodacom is the worst provider ever, after my contract expired i went to cancel it. I was told later after many calls and going there myself that my contract has been upgraded and not cancelled 😡😡making things worse i was told the manager at head office will call me after listening to the conversation between me and the Vodacom assistant and will call me in half an hour, 2day's later and haven't heard from them. Vodacom you are the worst and will be hearing from my lawyer soon
