Bad service

I went in to fashion world in Menlyn to buy an outfit, I took 2 same outfits but different sizes. I went into the fitting room, tried to fit but I couldn’t because the pants and the cardigan were attached together so I had to call for one of the ladies to come in and detach them which I don’t get why they attach them like that. Then I asked if I could take a different size of pants and a different size of cardigan because the other cardigan was too big. One of the ladies called the manager and when she came, she was very rude to me even though I tried to explain that upper body is not the same size as my lower body hence I’m asking for smaller cardigan. I’m so hurt and disappointed as I was looking forward to wearing the outfit on Saturday.
