Nedbank Personal loan settled but still reflects as owing on Nedbank's systems & Credit report

I've had an unpleasant experience with Nedbank. I got a personal loan from Nedbank years back which was really great and I was approved in minutes. My relationship with Nedbank went wrong when I asked to reduce my monthly instalment and was denied that because my account was not in arrears. So I had to let my account go in arrears because I was no longer employed and unfortunately it ended up being handed over. Last month on the 10/04/2021 I managed to finally settle my account and I received my paid up letter on the 12/05/2021 after making countless follow-ups. After getting my credit report I noticed that this loan in particular was still not up to date. on the 17/05/2021 I made another follow up to request that my account may be closed and was given this reference number by Tintswalo ***1, she advised that I will received a call from Nedbank legal department latest by Thursday. No one contacted me since then, today I called in again to make another follow up and spoke to Nicole who advised that the number I was given to call legal department was not correct, she gave me another number to call. I called the number and spoke to Zandile who still told me that she is not in the legal department, in fact she mentioned that legal department does not have a direct contact number instead she will give me a reference number and I must expect a call within 3-7 working days from legal department. She gave me this ref no. ***. In honesty am really tired of being sent from pillar to post without getting assistance. I need my account to be closed as I have paid it up in full. Please close my account and send me a letter that proves that it has been closed. I no longer want to wait, I have been delayed for too long now and I cannot apply for an apartment due to this status on my credit that is not reflecting truthfully. I need feedback by tomorrow please or latest by Thursday. I would really appreciate some assistance in this regard.
