Bad customer service- refund request

I signed up with Vuma in April and I've been pay at Pick n Pay and PEP respectively; and this was due to them always stating insufficient funds, in June I couldn't pay cause they decided to disable that service without telling me. I can't speak directly to them I get referred to WebAfrica who have been nothing useless when it comes to them helping me. I made an EFT on 01/07/2025 but my service was disconnected and I've been calling and texting ever since to get it up and running but to no avail. As I'm writing this I'm now being ignored on their WhatsApp Chanel and their agent hang up on me when I call, I asked for my money back and was told they can't reverse the money yet they also refuse to reconnect my fiber network. I'm now sent from pillar to post and being told about their accounts department who needs to allocate the funds and the 48 hours I was told to wait has since lapsed. I want my money back so we can part ways coz I never even had any agreement with WebAfrica to begin with
