change ur consultants attitude as it's slowly distroying the brand

my 74 year old dad went to make a deposit at ur Diepkloof square branch and after standing on the queue for a long period he was feeling dizzy and exhausted. He approached a consultant to explain this to her and got the worst answer and attitude. The lady just said" hard luck" I cannot help u. this is very painful. as it's the second time within 2 months I have to report such a behavior from ur consultants. We use ur bank but we are not appreciated. My father's number
