Out of Bundle

I receive an sms stating “ As per new regulations, you won't be allowed to use data without a data bundle. Reply 1 now to continue using airtime for out-of-bundle data services. Cell C“

So to my understanding this means that you won’t be able to use your airtime to make out of bundle usage Unless you respond 1.

This is where my complaint falls in. The out of bundle usage took from my airtime. So when I called into the customer care service I was told that I’m wrong and that I should dial something in order for that not to happened. The more I tried to explained to the lady above this is what I understood from the sms she kept on screaming down my neck. Which I find unheard of, I asked to speak to a supervisor she then puts me on a hold for a solid 10 mins. After waiting for “ntokozo” to transfer me to her manager i waited another 30 mins to speak to her Manager. Which I then had to drop the call because clearly they didn’t want to help me
