Elderly woman treated badly

My mom received the most shocking, disgusting service at the Phumulani mall branch, she asked one off the staff members to assist her to make an ATM deposit, since she is elderly and technologically challenged, Guess what the staff member said to my mom? " Why don't you call your children to come help you?" Is this how you treat your senior citizens FNB? Where is the respect? And elderly woman being told such ******* and treated like this says a whole lot about your customer service.
