Staff at Foschini Carlton Center extremely rude

I was with my fiancé on Sunday, we stepped into the Foschini store at Carlton Centre and I spotted a white shirt and jeans that I liked, I headed to the fitting room, only to wait at the door, as nobody was assigned to the fitting room. I eventually stepped in, just before I could make my way in, one of the staff member's VERY rudely snapped at me and said in Zulu 'Take a different colour shirt' and then walked away, no explanation, nothing. I then came to the conclusion on my own that I needed to try a different colour shirt as the white could get dirty and they wouldn't be able to sell it, however she was extremely rude and didn't show any kindness or professionalism. I was very angry and disgusted, I ended up leaving the store and bought what I had in my hands, I didn't want to shop around for more stuff, as I felt very annoyed by this lady's treatment. IT IS UNACCEPTABLE.
