Unauthorised charges on VODACOM account

I have just received my latest statement for June 2018. This is the 3RD complaint this year for unauthorised charges against my Vodacom account. Since 31 May 2018 I have again been charged for some entertainment service / DCB SGN game ******* that I did not sign up for. I repeat, I DID NOT SIGN UP FOR IT - I DO NOT play games either! VODACOM is debiting my account, taking my money, without my authorisation - THIS IS *****.! VODACOM needs to do something about their systems and ****s as they have placed consumers at risk by allowing this ***** to continue. We cannot be given some excuse each time that users apparently subscribe themselves, when we dont!!!

We are being de*****ed against our will. This must be investigated. Please remove these charges and return my money. If VODACOM cannot investigate and sort this out, then perhaps the next step is the Consumer Council and the Public Protector, because I, as a consumer, cannot tolerate this!
