Poor service at Nedbank

On the 23rd of December 2022 I contacted Nedbank as I was requesting them to place my bond on a fixed interest rate. I was told that I will be contacted within three working days. I was never contacted. On the 4th of January 2023 I contacted them again and when I wanted to give the consultant a reference number, he said no I can't use that reference number. He promised me that he will submit my request to the relevant department and they'll call me within three working days. I was never contacted. On the 9th of January I went to the Alberton branch. I was told they can't help me in the branch so I must call the call centre again. I called and I was given a new reference number and promised to be contacted within three working days. I am still waiting for their call.
