Vodacom prepaid call center's service is the poorest.

Hi. I loaded 200GB Vodacom data(prepaid) on the number *** in November. I've been having internet connection issues since 01/12/2022. I called the Call center for assistance from the 13/12/2022 and I didn't get any. I explained that I can only connect when I'm not home. But when I come back, my internet cuts off. A service request was logged and it was closed. But no one from Vodacom called me to find out what my issue is. 185GB expired on the 24/12/2022 as I was not able to use it. I was promised a refund and now I'm being taken from pillar to post. I spoke to Thulisile, Lefa, Vuyo (team leader)and today I spoke to Boipelo(team leader). She dropped my call, sent me an sms saying she'll call me tomorrow. They've now blocked me from calling the customer care line. Right now I just need my refund(R349) that I loaded the data with. So that I can throw away the Vodacom Sim card. The service that the Call center Agents and their Team Leaders give to customers is the poorest I have ever encountered. They are very ride and patronizing. Vodacom can't refuse to refund me whereas they didn't provide me with what I paid for. Everyone promises to call me back, but they don't. I just need my refund. Why is it so hard to get it?
