Service of Pick n pay on Darwin

This evening myself, my brother and my brother in law was at Pick n pay on darwin, our weekly go to supermarket. This evening I had a problem with one of their front line management a woman called Gertel, the labelling was completely wrong in the chips aisle, and when the cashier asked Gertel to fix the pricing she rudely said" I'm not going to give it to you for this price " and when I said you have to fix your labels she responded there's nothing wrong with it!! She is very unprofessional and bluntly rude! I am utterly disgusted in the service I received. I have been shopping at Pick n pay on darwin since they opened and never received such a awful service.
