How is it still impossible to cancel a Vodacom data bundle subscription?

I would like to cancel my recurring data bundle subscriptions, but there doesn't seem to be any way to do this via any of the Vodacom interfaces. This despite numerous complaints I found on online forums and social media that the option to easily cancel a recurring data bundle doesn't exist.

This is super ***** and creates the impression that Vodacom is making it difficult on purpose. I get it, you're in the business of making money, but by the same token, your customers are in the business of surviving right now. I don't need the extra data and hardly ever use it, so it's a complete waste of money and I have a right to be able to cancel it.

As a customer, I should have full autonomy to manage my data spend. Is it too much to ask that you make cancelling data subscriptions as easy as signing up for them?
