Braam Square FNB Manager who is uninterested in assisting clients

I visited the Braamfontein branch yesterday and I must say the Branch manager Thuli Mhlongo was very rude. As she was addressing me her body language did not show any interest and her facial expression showed she cared less about my current frustration. As a manager in the retail industry one thing I learned is how to champion customer service and assist to the best on my ability. When I questioned her why does she look so uninterested to assist me her response was do I want her assistance or not. I'm not sure if this meant she is doing me a favour as she is employed by FNB and receiving a monthly salary for service she needs to render to me the customer.

FNB is a well established bank which has been in business for many years and as a new client I must say the customer service I received from this individual left a bitter taste in my mouth. Can you please ensure to take her to customer service training so she can understand how vital customers are to the business
