Nedbank offering an extremely poor service

I have been struggling with closing my Cheque account *** with Nedbank since December 2024. There have been several follow-ups, both on emails and calls, to request that this account be closed, but Nedbank seems not interested in closing this account. On 8 January 2025, I made another follow-up using their chat platform, and I was given several processes to do, including reducing the balance to less than R10 before the account could be closed. That I did, and my request was sent forward by the consultant who was on the chat. She informed me that a Nedbank consultant would then call me the follwing week before the account could be closed. That call never happened from Nedbank. I made another follow-up after noticing that there was an sms indicating that there was another maintenance fee of R250 charged for February on the same account. At this stage, from the 8th January until the day of the follow-up, the account was no longer reflected on my banking app profile. I made several email follow-ups including using the reference number ***, still Nedbank did not do anything except to send the automated replies. In March 2025, I received a call from Nedbank about the account closure issue and this was after I escalated the matter to their complaints department. I was informed that the maintenance fees would be credited and therefater they would close the account. Today the 28 March 2025, the account is still not closed and has charged another R250 maintenance fee and the worst part is that today the account is reflecting on my Nedbank app profile almost after 2 months of disappearing while it remained unclosed. This is quiet so bad I do not understand their reasons for failing to close my account. It such a poor service.
