Rude teller!!!

I am so furious, I just came from Pick n Pay in Bramley Johannesburg & a teller named Constance Chipuma was very rude & didn't want to help me. The level of attiude she had was a huge disappointment for both her & the store. I reported her to the store manager & was told most people complaint about her so she will take I up with her. I feel she should not be working there as she is very useless & arrogant. She laughed when I reported her as she knows nothing will be said or done to her. She knows she always gets away with her rude behavior to customers. It is unacceptable. I am never shopping there again!!!
