unhappy customer - Credit card

I am very Disappointed as this is the second time I am writing about this matter to Standard bank. I had a credit card which was paid up last 2016 and still to date it shows on my credit report transunion. I don't understand why this still shows a balance and i even got a paid up letter. should this accounts not be updated automatically because now it is affecting my purchase of property. can this be resolved please urgently. i sent the paid up letter to Nonhlanla Mthobeni a fact which i don't understand that i have to send standard bank a paid up letter when it came from them in the first place. Transunion shows account number ********** ********** 10 balance of R60388 Ennie Josias
