Poor internet service provider

I have been a Rain customer for several years, using the SIM-only option without any issues. Recently, I upgraded to the Rain One package, which was promoted as including unlimited 5G, plus two free SIMs for data and calls, all for a price of R535 per month. However, I am experiencing significant challenges.

Firstly, my area only receives 4G coverage, and I have been struggling with poor reception daily. Secondly, my recent debit order reflected an amount of R1130 instead of the expected R535.

When I contacted Rain customer service, I was informed that I should have canceled my previous SIM-only plan, which has resulted in the additional charge. I was also told there is data usage linked to this SIM, even though it has not been in use for the past two months. After waiting on hold for 20 minutes, I was told nothing could be done regarding this charge, and that the additional SIM would remain active until the end of the month, even though I had no intention of using it.

I am very disappointed with this situation, particularly because I was not informed that I needed to cancel the previous SIM when I upgraded. I do not believe I should be charged for a service I am not using, and I kindly request a resolution to this matter.
