Rain billing poor poor service

Im truly disappointed about Rain services and how my query has been handled. I have called support line about 3times now and the feedback I get is very inconsistant.

I was on a 4G unlimited plan (R499) and I called in to enquire about how I can upgrade to a faster connection. I was advised by support/sales agent that there was only rainOne 5G package that was available. Agent confirmed that once the 5G is active, it will show on your end and the 4G unlimited package was going to be automatically discontinued.

I activated the 5G package on the 23 May 2023 and was billed R559 which was paid immediately. To my suprise, on June 30th I was being billed R1058, double of what I purchased. When I called support line, I was told that the 4G service was never cancelled and the issue will be escalated and ill receive a call with an update. Till this day, im still waiting on a call. I called rain for a follow up 2 or 3 of agents told me that this issue was escalated and I was going to get a call from an agent, to this day im still waiting! One other agent told me that even though I was advised that the service was going to be automatically cancelled, her team leader told her that im liable to pay even though she saw that it wasnt been used. I find this to be a total ripoff.
