Worst customer service and no support after billing errors happens at Rain

I have been overcharged by Rain for months, and they have refused to give me a refund for the R1000 that was ****** from me. I have filed support tickets as directed, but I have not received a callback, and they have disconnected my internet because I don't think I can continue to pay until they have acknowledged the billing error. The situation is getting worse every day, and I'm not receiving any help or feedback. As a result of Rain failing to address any of their problems when they were initially reported, I'm currently without internet and without support. Ticket ***5 has been unanswered for three days, despite being promised a call within hours. I am amazed at how poorly they handle their customers. It’s incredibly frustrating to feel ignored and left in the dark, especially when reliable internet is essential for daily tasks. I hope this situation can be resolved soon, but I’m beginning to lose faith in their ability to provide adequate customer service.
