Unwanted Promotional messages

I have been trying to stop the promotional messages to no avail. I called vodacom after a hustle did I get hold of a human agent after trying their bot Tobi, which was an extreme frustration to interact with. After speaking to an agent months ago she assured me that the messages would stop but they didn't. The ussd suggests that I'm not opted for any promotional messages but I keep receiving the unwanted annoying messages.

Surely under the Popi Act vodacom should be taken to task for this
