Vodacom - Vodacom Add to Bill - Other

I am so disappointed with VodaCom. After they gave me a good deal because I am Unemployed and cannot afford everything with a monthly premium of R268.70 - R104.35 for a Smart S + Line Rental they slapped on R188.79 for Vodacom Add to Bill - Other which I do not know anything about. They should ban any 3rd Party add ons. They make a hell of lot of money by these ********** transactions. When I phoned them they said it came from Telecom Games, they did stop it though, but I still cannot afford to pay that extra R188.79 on my bill that was not authorised. I am not going to pay that as I have no prove that I subscribed for such a service that bills something like R7.00 a day.
