Bad service at Foschini Parow Centre

The Parow Centre branch service is shocking. I asked this lady she was on the floor packing shoes (highlighted blond and grey hair) to get me a size 6 on the shoes i sas on display. With so much disgust on her face she asked me "why dnt u take that one" i mean the shoes in worn out already from being tried on, why must i buy that with my money when theres still plenty of shoes available. She just left me with so much attitude i couldn't understand. Im shocked.
