Very disappointed and angry ..

We just drove off from Shell Filling station in kenleaf. My husband wanted to withdraw money from fnb ATM. There was a lady cleaning there,even though she can see that people are waiting to withdraw she kept on repeating wiping the ATM with no care that they are waiting. Then,when she went to clean the outside glass, after close to 5 to 10 minutes of people waiting for her, when the front lady go in to withdraw, she then tell her that it's not working. How unprofessional of her, she could have told people long time that the ATM is not working instead of letting them wait for her to finish whatever she was doing, only to tell them that its not working. I am so disappointed,since it's my favorite filling station.
