Account

I think this is the second time I’m writing a review on rage because every time I apply for credit and get rejected I’m reminded of them. Never open an account with Rage shame. They listed me as a slow payer over R50 I was not aware I’m owing to them. I remember paying them full amount and never taking anything again. After a year I tried opening an account in another store got rejected. I tried others still the same thing. I called Transunion and found out I owe rage and they listed me as a slow payer. Paid it up that R50 as angry as I was. They told me the person I paid to must’ve not punched the whole amount and rounded it, idk what bs is that. It’s been a year now since I closed down that account but I still can’t get any credit to build my credit score. If anyone has been in the same situation, how did you fix your credit report? Which stores or creditors give you the benefit of the doubt?
