Vodacom the *******s

I received my vodacom bill and to my surprise I've been charged for entertainment services and content services amounting to R573.97. when I contacted vodacom they say i subscribed to these services, which I've never. I really don't know how many other innocent people are being ****** like this. Why would i subscribe to these things, and add extra cost to my bill. To me vodacom are just here to rip us off. This is not the first time I've had an issue with vodacom.
