Payments update at credit bureau

I have a credit card with African bank which I am paying monthly through an arranged debit order and I do not miss a payment. In 2016 I had financial challenges and I was under credit review. As my financial status improved I cancelled the credit review and started paying the companies I owed myself, African bank is one of them. I sent African bank the cancellation letter from the credit review company and asked you to update my payments at the credit bureau, to date you haven't and it is negatively affecting my credit record. I have made many calls to African bank and you always promise to update it, but you don't. It is over two years now. I cannot access any credit because of them not updating my payments. Your company sends me aknowleding of payments messages every time they receive a payment but my credit report is ruined because of your failure to update my payments. Someone please intervene. Your treatment towards me is not fair
