Unauthorized charges and additional handset fees

I upgraded my phone in March 2017, as i still had 2 months left on my contract, I had to pay a handset installment for April and May 2017. In June 2017 I was still being billed for the additional handset. I managed to get hold of the billing department to have the additional handset fee cancelled and they credited my account. To my dismay, in December 2017, I noticed that I was once again billed for the additional handset. I contacted Vodacom again and they assured me that it would be sorted out. My January 2018 statement again reflects the additional handset fee. Why is it so difficult to cancel this? I am being charged an extra R 324.56 a month!

I also have additional charges for Vodacom Live content which I personally have not subscribed to. I have no idea what it is for. Why is Vodacom adding services without our consent? I want all charges refunded with immediate affect or I will have my contact with Vodacom cancelled. I was not asked if i wanted additional services neither was i informed of the additional services. This is ****************!!!
