Vodacom charging for services I never requested.

I have noticed that Vodacom has been charging me for Content Services, supposedly for content that I subscribed for. I have NEVER done that. I Googles the service and see that it is a US company that provides games and they have partnered with Vodacom. What upsets me most is that nowhere via Vodacom's website or app can I see what I supposedly subscribed to. After half an hour on the phone with the customer service , where I asked that my query be escalated and my money refunded) I was asked to dial a USSD sms service to see what I have subscribed to an to unsubscribe if I required it. When I did so I was informed that I have NO subscriptions!!! So what am I being charged for then? I wonder how many other client have been ********** like this? It shocking and the business practice is tantamount to theft!
