Vodacom and GameMine

It seems a recurring problem with Vodacom. GameMine. They must also gain from billing clients for this service. I get a notification only at the end of the month to say I have 3rd party entities included in my monthly bill. I then cancel it (the previous month) and still get billed the next month. This is unacceptable. Vodacom App allow you to cancel third parties, yet costs still reappear. They just make you feel safe, but then bill you again - how is this possible? Is there any legal entities wanting to make money from suing companies like Vodacom? This must be an oppertunity. I wonder what the POPI act will do with this?
