The worst customer service experience EVER!

I am honestly appalled by the treatment that I am receiving from Rage. Last year my name was reported and listed to the credit bureau for non payments, twice, even though I have never missed any payments or made any late payments. The one month of August 2025 I in fact paid my account twice, one payment in store, the other via eft (my sister). Needless to say, I have been begging and fighting with Rage to clear my name after I have given them the proofs of payments. My name is still marked as missed payments, which obviously affects my credit score (which i have worked so hard at to get to a respectable score) and my credit score also affects any possible business dealing for my (private company). Now again, I owed Rage 75. 99 in May of 2026, I decided that I won't pay more than whats expected since the previous year's nonsense. So end of May 2026, I gave them 60. 96 because that was my installment as per their sms. I paid the R15.99 at end June 2026. I didnt buy anything in May, June, 29 July 2026, I bought for R590, didn't expect to pay anything until end August 2026, now again, my account has again been added on the blacklist as a slow payer, apparently I owed Rage R1.23, for what I don't know. I never received any notifications and also because I know for a fact that I didn't owe them anything. And to top it all off, they expect me to pay R206 for two months (apparently I'm in arears). I don't know why Rage is harassing me like this, this is victimization of a different kind. It seems as if nobody cares or knows how to sort out this mess. Meanwhile the owners of this business is just making up money without respecting it's customers. Experian wants reference numbers that Rage aren't capable or willing to assist me with. Taking legal action against Rage is my only other option.
