Unattended due to insufficient funds

Fnb pinecrest in pinetown has the worst customer service, the manager is Avashni Sigh and the consultant who was helping me is YOLO BUBU. I went to the branch just before 5 as I needed a bank statement, and was told to go to the atm. So I went and the was an error, so I went back to the branch and they were just making fun of me saying maybe I am not fami**** with the atm machine, I felt embarrassed but anyway the lady YOLO bubu went out to the atm with me and again same error message and eventually checked my balance and she just said that is why cause I had no funds, now we went back on the branch and she just shouted to her colleagues that I don't have funds in my account and left me by the door not knowing whether is she still helping me or what.

She decided not to bother herself explaining to me and she just left me hanging just like that, I felt very small considering that I am a client, does this means i should not bother asking for help at fnb if o don't have funds in my account? Very bad customer service indeed. Shocked to know that such a big brand still keep people like YOLO in the business.
