ABSA not updating your credit information

I recently owned R66 on a student credit card. About a month ago I went to pay the due amount and closed the credit account. However it seems like ABSA has never updated my credit score information (according to the amendment to the National Credit Act require credit bureaus to immediately remove all negative data if you have repaid the debt in full, this hasn't been done). Now that I want to apply for a cellphone contract, it has been declined due to a bad credit record (I don't have any debt, nor credit cards). This is absolutely pathetic, I've done my part, now where is ABSA doing there part??? Once this issue has been resolved I will absolutely close all remaining accounts at ABSA. Disappointed to say the least.
