Vodacom *******ly supporting Opratel/Nowmista by adding this to contract users' accounts without user knowledge

Vodacom have without my consent added a subscription for Opratel/Nowmista to my account since May 2017. When I queried this from the call centre they said that this is out of their hands, I should call Opratel as I subscribed for this (never mind the fact that my contract is on an Iphone). With an Iphone you can only open subscriptions on the AppStore or through Itunes and this get deducted straight from your credit card. Is Vodacom *****ing money from contract users in order to support Opratel/Nowmista?! Surely if they are collecting the money on behalf of Opratel/Nopwmista they have control over the subscriptions?! VODACOM, THIS IS THEFT AND YOU BETTER GET IN CONTACT WITH ME AND REFUND ME OR I WILL PUT THIS IN THE HANDS OF SOMEONE THAT WILL FIND OUT EXACTLY WHAT YOU ARE BUSY DOING.
