One and a half year later and still showing outstanding balance on credit card

I was under debt review until July 2016. My FNB credit card was one of the items being paid off. I received a letter stating that the account has been paid up and the account is closed. I am a Standard Bank customer and I ordered a new cheque card as I got married and had to change everything. I AM NOT ABLE TO UPGRADE MY PACKAGE AT STANDARD BANK DUE TO THE FACT THAT IT STILL SHOWS THAT I AM R11595 BEHIND ON MY CREDIT CARD!!!!! The same credit card that has been settled and closed in July 2016. I called the Debt Review department yesterday and they promised to submit the paperwork to ITC and sort it out ASAP. NO ONE HAS CONTACTED ME TO LET ME KNOW IF THIS HAS BEEN DONE OR NOT!!!! I AM BEYOND DISGUSTED
