Menlyn Arc Store is unprofessional and has rude unhelpful unapproachable staff!!!!

I went to the arc store in menlyn and a supposed make up artist eventually assisted me after being ignored by her several times. She was abrupt , short and rude to me. I tried my best to be polite to get a better response while helping me but she really acted as if she didn't want to do her job. She app**** foundation very roughly onto my face with her fingers several times, then took me to a desk where she dropped a used wet and dirty foundation brush on the floor, then on me, messing my pants, she then used it on my face! She app**** it to my face very patchy and wiped my face with a wet wipe instead of makeup remover several times. She raised her voice in a condescending tone everytime I told her something , and eventually I felt forced to buy whatever she recommended.. then left me looking mismatched with two different shades of patchy and blotchy foundation on my skin to walk out of the mall looking like a complete mess. I got home and immediately washed my face because it was reacting so badly, I ended up now having a huge break out with red patches all over my face.
