Non-Roaming data still not working after multiple phone calls and case numbers.

I have a 50Gb data bundle that I bought in Nov 2020. Since Cell C moved over to the Vodacom network my bundle stopped working. After multiple phone calls and a couple of a case numbers there has been no change. Some of case numbers aren't even in the system anymore. Other case numbers say my problem has been resolved without any communication with me to check.

So now is sit with 47Gb of a bundle that I am u able to use. It's time for a refund and/or a contract cancellation.
