I’m extremely disappointed with Rain’s service and customer support

I’m extremely disappointed with Rain’s service and customer support. I was double billed due to a "system glitch," and despite reaching out, I was told there’s nothing they can do until Monday. Meanwhile, I’ve been left without internet for two full days, and support agents can only say they’re unable to help because of the system issue. I’ve already paid R588.72, which should cover my previous month and pro rata for the new router. Now I’m being asked to pay R826.00 on top of that — which I simply can’t afford, and shouldn't have to. To make things worse, I was told my first month would be free with the new router, and that’s clearly not the case. I’ve kept my account in good standing and always paid on time, yet now I’m being treated like this. Once this issue is resolved, I will be cancelling my service and returning the router. I will not be paying a cent more for a service I couldn’t even use.
