Settlement not refleting

My name is Nothando Nzuza.. I'm so much frustrated and I can't even eat. First it was a debit order debiting my account without my knowledge. Now I made a settlement with Capitec on the 31 of October. I do have proof of settlement. But Nedbank is saying that they can't see anything on their side. I have tried and visited Kwamashu Bridge City branch and they said they cannot help I need to phone. But when I try to call Nedbank no one is willing to assist. I have even sent emails to show proof. But no response. I'm really really frustrated and don't know what to do anymore.
