Vodacom False content service charges without any feedback

I discovered that I was being charged R7 a day for content services I never subscribed to. I did not even know such a service (WeFit of BeFit or something) existed. And I most certainly did not subscribe to it, and also never received anything from this supposed subscription. I logged a query with Vodacom customer care on 9 Oct. Today is 27 Nov I still have not received any feedback. When I call customer care the only answer I get is that it has not been resolved yet and I cannot escalate it and I simply have to wait. In the meantime I must pay an amount almost double my usual bill. This is plain theft from Vodacom. How can they simply take my money and give it to a third party without my knowledge or consent??? I have been a loyal customer for 28 years, and then I get ****** like this and absolutely no assistance.
