Injustice - shocking customer service

I am paying customer each and every month. At the end of June 2024 I paid my account at Gateway Mr Price Home and I asked the cashier how much is my installment and she advised it was such. I paid such amount and assued that my due was paid for the month. To my dismay i pull a credit report now and I am shocked to see that MR Price has handed me over for a short payment of R50. They have listed me as a slow payer even though my account was paid. In the month i got numerous marketing messages and emails but not a single referred back to me stating there was a short payment. THis will now take 3-6 months to clear of my name for R50. Shame on you MR PRICE, this behavior is not on...

I called your customer care line and spoke to the first person "SNE" who put me on hold and the call got cut so i called back and spoke to "Balu" with a reference number *** and she was of no help at all.

Shocking customer service, i so want to pay off this account and close it and then warn other friends and family and customers about this horrible injustice.
