I'm extremely frustrated

I'm extremely frustrated with the experience I've had with Rain. After upgrading my router to Rain 101, I was charged R1272 in monthly fees. When I called to query the deduction, I was told I should have cancelled my other subscription. I explained that I had upgraded and app**** for the new subscription. The representative stated that the other subscription was cancelled.

The issue is that I've been charged the same monthly fees for 3 months, and despite calling, I haven't received a clear explanation or resolution. I'm unhappy with the service and feel misled. On Monday, I plan to escalate this matter and lodge a complaint, as I believe Rain is engaging in unfair practices."
