worse service ever

I was atRustenburg Game Waterfall Mall I was looking for a memory card I stood there next to the cashier for 30mins because they was no one to help at the cellphone site he tried to call someone to come call someone to assist us but there was no one to help ,while I was standing there the was another customer at the jewellery site screaming for help until one guy came in shouting at the two ladies cashiers standing at the intercom that anyone can go in and assist and one lady answered back to the guy in her language that she doesn't want to learn how to assist that side ,after that's when I approached them again and ask if they also don't want to learn about memory card as well that why we will wait for ages to be assist and she said the front is not the only place where memory card are placed and i ask her why she didn't say that in the first place and she stared been rude and gave me her back walk away from me I told her I want to report her and she said I must go ahead and I said so you don't might loosing your job she said she doesn't care she is not scared of anyone .This is a serious concern if the company is keeping people with this kind of attitude What are we saying to the company's image ,integrity and most of all to the value of the company ,I really want to know you code of conduct this is a serious issue for a big franchise like Game and mind you she was screaming while saying that .
