Bad app, bad call center, ******* practices

I have not opted in to out of bundle data. Every time I have had bundles run out, I get a notification bar telling me to sign into Vodacom to buy more data. Last night I forgot to switch off my mobile data and at midnight my bundle ran out. Instead of making me log back in, Vodacom has decided that I now need to set an "Out of Data Limit". This has never been a thing before. According to law, you cannot use airtime for data unless I opt in for this service: https://www.timeslive.co.za/news/consumer-live/2019-02-11-new-data-regulations-what-cellphone-users-need-to-know-to-stay-connected/?fbclid=IwAR3Rgp63VEC6UqBhmUcK5hqwZmanJ8VXCZzNNWJ19U0uqTHltYOeiBhMz1g Vodacom just decided that the rules no longer apply to them. No one can show me where I opted in.... But I have to opt out? That isn't what the law says. The agent I called was rude to me, the app said "As an act of good will we will refund you." but social media and the call center will not honor this. I am honestly looking at moving providers as soon as I can- its not longer worth the high prices and poor service.
