Unsolicited data

I have a fixed uChoose Flexi 230 Line Rental with Vodacom for R785.99 which excludes data because I have an unlimited data contract at home. Over the past few months I have been billed way over R1000 by Vodacom when I visited 2 of their store they claimed to be offline and could not help me but will get a call centre consultant to call me back which never happened. I recently contacted Vodacom call centre spoken to Gladwell Mahanyele after a few attempts I was told I requested a 3gig data in April 2020 (which I never did as I have unlimited data with opposition service provider at home) and they activated same for the following 2 months without my consent. The fact that they sent me a message confirming data does not necessarily mean I requested for this data especially that this data was never claimed by myself after it was activated! When I ask why didn't they contact me to confirm such a request as the April data has never been used 3 months later gave me a lousy excuse that they did not want to harass me, how convenient? I told the agent I don't need vodacom data and he must cancel it so I will continue with my normal contract payment and he refused that arrangement. It does not make sense that I have to pay for the data I never request nor used for Vodacom to withdraw / take back its data ( basically he is saying I must pay for Vodacom account for vodacom to withdraw their data that I never needed nor used so basically Vodacom must benefit both ways at my expense, whole lot of *******!! I requested to speak to someone senior and was given a name of Ms Masego Motlephi that will call me back to resolve my complaint and since then 09 July, 2020 no call has been received from this respective supervisor. This is very ********* business practice for a company like Vodacom ******** customers at given time it must stop now!!
