Body shaming and Rude Staff

Went to Mr Price at R55 in Centurion there was a long black jacket I had seen and tried on earlier. Staff member said they were finished and I asked for one on the mannequin which was a size S. A really rude staff member told me I was too big to fit into it and she wouldn’t take it down for me to try on again. I felt body shamed and belittled. The staff had poor customer service
