CENTRAL SUPPLIER DATABASE - NEDBANK PLEASE VERIFY MY BANKING DETAILS

I have shifted by small business BANK account to Nedbank over a year ago. September I got a small contract with the government institution. On the Central Supplier Database I still had the old bank account listed for payment. I then went on the CSD system to load my Nedbank details as is. It is said to take 4 working days max for the bank to verify the details. on my case, its has been rejected each time with a different error massage 1. The ID of the member does not match the bank account, 2. The Name of the company does not match the account, 3. Please make sure the details captured belongs to the legal entity....

I have tried visiting the bank but no one seem to understand what i was talking about. I tried the chat app on the moneyapp. I have invoices pending for payment and the client is getting straitened with me because the can only use details captured on the system and verified by the bank.
