Vodacom - Unauthorised daily subscription debits - Hunky Dory

I have made this rating after doing an internet search to try and establish details relating to Hunky Dory, On contacting Vodacom after having suddenly found that I was out of airtime for no apparent reason, I was informed that an amount of R10 per day was being debited in relation to a daily Hunky Dory subscription. This without any knowledge of mine, They have arranged to cancel and block this in future, however, given the fact that they have knowledge of the ****, it beats me that they cannot blacklist and block any subscriptions logged by this crowd. Would be interested to hear what they have done and what can be done to protect subscribers
