Vodacom - Billing for Vodaphone Live services ********** and out of bundle rates

I received a bill on my son's contract in excess of R4000.00 and I was notified that he was charged for out of bundle rates. Previously myself and my sons cellphone would stop browsing and we had to purchase a once of to continue browsing. After querying the bill today and asking for a itemized bill I noticed a additional charge on my bill for the amount of R253.00 on my account for Vodafone Live that has been added since October 2017 till current. The Vodacom Customer service representative told me that I subscribed to a service . I do not subscribe to services and all payments are done via the Apple Store on my credit card. I believe that this practice is highly ******* and hundreds of customers has been subjected to this ********** practice by Vodacom South Africa. I was informed by Vodacom that they would request a credit but that they would only pass a credit for 6 months and not the whole period. They have suspended my line and keep on billing me for Data packages that I cannot use either that was purchased. I need this resolved expediently so that I can have my services reinstated.
