STD Bank: Unfair Credit Listing

Good day, I have taken a STD Bank revolving loan of 72k and I managed to pay it off by 29 May 2018 and they provided me a paid-up letter which provided me a discount of 20%. I have later requested my credit record from transunion, only to find out STD Bank still listed me as owing them an amount of plus 15k. I later called them from the 15th June 2018 till today they have not yet sent the instruction to the credit bureau. The problem with this, I can't buy a house for my kids as no lender wants to deal with me.

I then app**** for a home loan through STD Bank as they are the one who wrongfully listed me, the irony they declined me as well as they claim the credit bureau shows poor score, I asked them to look at the account that show unpaid. The consultant said its STD Bank, I then asked him to check my account that he claims is unpaid, he then its paid in full.

I later asked him why is he declining my application, he said its not his section to deal with this. He can not approve my application on the bases of the faulty bureau.

I'm now puzzled!!!!!
