Content Service charges on Vodacom account :(

I have been billed for content services for the amount of 134.86 that I have not subscribed to, I don't even play games on my phone. How can any service provider allow these billings? I saw on the internet that I am not the only one being charged for content services, is this now a new thing for Vodacom to collect millions from their unsuspecting clients. You have a debit order you wont look at your bill just pay? Then I must pay again to stop this content services which I have not subscribed to in the first place. This is not the first time I am having bill related queries on my Vodacom bill and they have stopped their e-mail queries as well now you have to sit on the phone for hours on time because we are experiencing high call volumes :( so you are getting nowhere with them. I want these charges reversed asap off my account or I am going to stop my Vodacom subscription asap.
