Constant WASP hogging on my account regardless of any blocking settings, requests to zero my spend limit, etc

Constant WASP hogging on my account regardless of any blocking settings, requests to zero my spend limit, etc. Nothing works. My bill is some months more than Double! I have logged so many calls, Vodacom is either clueless or complicit. They receive huge kickbacks from these WASP subscriptions, so I understand, but the money is coming from our pockets! Shame on you Vodacom!
