Poor service at Nedbank Durban North

Today I went to the Nedbank branch in Durban North to collect my ID, once I had collected my ID I went to request at the brunch for my surname to be changed on my Nedbank account. Was told to take a sit of which I did. A while later a white lady walked in and she was directed to a teller that will assist her. Mind you I was the only one waiting in the bruch The 3 ladies (staff) continue with their conversations as if I was not there and a while later one of the ladies came to me and told me I need to wait a while longer because the supervisor is in the volt and she has no idea when she will be out. That time I request for an hour at work to sort out my account. I left without being assisted and I was very disappointed and m thinking of changing my account to a bank that treats all there customers equal and not discriminate because of my skin colour. The 3 ladies were all black looking down on another black lady.
