Vodacom allowing content Subscriptions (RTST) without permission

This is terrible: Vodacom is allowing unsolicited subscriptions to people's accounts, that cause airtime to be eaten away without permission.

Yesterday I received an SMS saying that I had successfully subscribed to RTST. I did not do so, in fact, I don't even know what that is or what stands for.

Additionally, it says that the subscription is free for 1 day, and then charged at R10/day thereafter.

I had to dial *135*997# to stop a subscription I hadn't even signed up for. What if I didn't see this SMS quickly enough?

This is unacceptable behaviour in a time when South Africans can barely afford anything, now our mobile operators are still being scaly trying to ***** our money. I'm very disappointed in you, Vodacom.
