Bad experience

I got a back customer services from all the stuff at Jubilee hammanskraal mall from the teller by the name of Tebogo sethole who lead all stuff to act nusty on me... And apparently it's not the 1st time.. You greet them they don't greet back, I even informed them that I'm actually on lunch hence I am working at the the bank premises.. The attitude was "she said she on lunch" they laughed about it and said ohk thanks for informing us with an attitude kindly address the issue, especially from the Tebogo Sethole
