Good bye fnb

This Saturday I stepped into the very branch at which my account is held only to meet a woman named nomathemba who comes asking me what I'm here to do I told her that I have a simple request I just need proof of residence she immediately responds with a \I don't care"attitude and says they can't help me at the moment I must go to another branch when I asked her why she rolls her eyes and tells me it's going to take long this shocked me because first of all it has never taken me long to get proof of residence and second of all that's her job wether she likes it or not.. I would like to know what fnb plan to do about such poor efforts by the employees if no response is received by Saturday then sadly I will have to find a new bank which will be tough since i have been banking with fnb since the age of 12"""
