Disgusting employee

I had visited the branch to get a proof of residence. Despite nobody being there, the guard said I should come back in at 4pm which was two hours later. Despite that I had come back half an hour later only to be assisted by an extremely irate consultant. The consultant was very rude from the onset. I had requested a proof of residence. She continuously gave me proof of my postal address. After waiting a while, I had asked to print the one from her banking platform as always done as I knew that would be correct. The consultant immediately got aggressive with me by stating that I should not tell her how to do her job. SHE had then after continued to verbal abuse me raising her voice. I had then told her that I was going to lodge a complaint and I wanted her employee number, which she had refused to give me. I had told her that I was going to lay a complaint and she had told me that my fathers not Mike Brown, so I can do whatever the hell I want. The service and staff at Nedbank are just progressively getting from bad to worst. I can't believe that this is the image Nedbank wants to up hold! Their staff should really be trained on FICA. The incompetence and aggrogant behave I received
