Nedbank Poor Customer Service

I am very unhappy about the service I received at Nedbank. I contacted the Nedbank call centre a few times, send emails and went inside the bank, but got no assistance. I was under debt review and wanted to settled my homeloan immediately. I was told at the Mitchell's Plain Promenade branch, the settlement amount will be given to me over the phone and I can make the payment at the bank the same day. Standing inside the bank speaking to a consultant on the 06/01/2023, holding for more than 30 min, just to be told I must request a settlement in writing again, while I'm still talking I got cut off. I phoned back again and was holding again for more the 30min, only to be cut off again. They also refused to help me inside the bank and said I have to call the call centre.
