Nedbank Personal Loan Settled but still not closed

I have a Personal loan with Nedbank that I managed to settle on the 3rd of August 2020. I then called to notify the bank that I had made payment and would like to have it closed and get a proof of settlement. This has been a mission with constant calls since the 3rd (long for that matter), email requests to prove that I had made the payment and empty promises that the account would be closed in a certain number of days. I have dealt with numerous agents in the past 11 days who have all requested the same documents and seem not to know exactly what to do to close a paid-up Personal loan account. I have sent out numerous emails with the proof of payment to all the agents that have answered my calls only to wait in vain. I have been given multiple ref numbers to assure me that the closure process has been initiated only to get a different response when the waiting period lapses. I have gone the extra mile to send the requested proof that I have paid-up my loan to the *** email and there still hasn't been any proper feedback. It's amazing how the urgency is this terribly slow when a client makes payments to settle an account but follow-ups on outstanding accounts are done with urgency. Very ridiculous service from a reputable bank. I have other pressing priorities that depend on me receiving and sending the proof of settlement that is now at risk because of *********** Nedbank consultants!! ALSO, debit orders are still running though I settled the account. I am totally disgusted!
