Rude teller at Ned bank

Please could we have an efficient and people oriented staff at Ned bank Durban central west. At 12h00 there is one teller and one consultant at enquires, the rest of the staff is busy with coffee and other things. 12h00 is generally lunch time and for a peak hour like that it would be nice if you scheduled more than one teller. I waited for almost 45mins in a queue at this particular branch on Wednesday afternoon only to get to a teller who asked of I was I the account holder and why didn't I go to the branch in musgrave? What has it got to do with her which branch I go too?? Mind you there is a long queue of people waiting to be served while she is arguing with me, she wasn't even wearing a name badge, I surely won't be returning to Nedbank durban central west, I'd rather drive to musgrave to get proper efficient service. I've never been humiliated like this.
