High disregard for clients

I closed my business account on 24.03.2023 and provided an account number for the remaining balance to be transferred into. I was told by the banker Johanna Magoele that the money will reflect within 2 business days. However a week later, nothing happened. I then followed up via email on Monday, 03.04.2023 but no response. I made another follow up on Tuesday, only to receive an out of office reply with no return date but a forwarding email for urgent matters. I then received an email from Heidi who requested Tshidi Matsosa and the 5th she sent me an email asking for the account details I had already provided to Johanna. She promised to check and revert back to me but to date, I still do not know what is happening. This situation is not only frustrating but leaves a bitter taste in my mouth when I hear the name Nedbank.
