Vodacom content services charge

Absolutely shocking. I have been a vodacom customer for years on end. Suddenly from february 2016 I am charged almost R400 per month for 'content sevices' for which I never signed up for. When I phone vodacom to assist they direct me to a 3rd party provider. They say I must get a refund from them??? Who gave vodacom the right to deduct money from my account for services I did not sign up for? Vodacom this is pathetic. I am very disappointed in your level of service and commitment to help a customer. I received an sms to confirm that the subscription has been cancelled, but to my surprise I am still being charged daily!!
