Rude and unprofessional employee

I am so disappointed with the service I received from Rage at Eyethu Mall, I went to the store on the 15th of December at 9am to buy shoes. However the shoes that I wanted was not the correct size so I asked one of the ladies for assistance and instead of her explaining to me that one of the cashiers will assist she just turned her back on me and went to the back leaving me standing there. When she came back I confronted her saying that am still waiting and that's when she started being rude and shouting at me 😳 the worst part is she didn't even have a name tag on, actually they all didn't have name tags, which made it difficult to identify her by name.
