paid up letter

I had a credit card and garage card with Standard Bank, which I have since paid up. <br> The credit card is still linked to my cheque account and I can still see the negative balance. I went to the bank about two years ago to inquire about the matter I was told not to worry about it. <br> In April 2015, I app**** for credit with another bank and I was told that I owe standard bank, I went to standard bank and they confirmed that they know that I have paid up both accounts, but they still have them owing on the system. They promised to correct their books. I waited for two weeks, then made another call, I was told that the consultant that helped me did not update the system. The lady who helped me on that day said she will update the records and that I should have paid up letter by May 8, 2015. I then received an sms confirming they will get back to me with my enquiry on May 8 I am still waiting a week later. <br>
