PEP Flora Centre Rude Manager

I went to Pep in Flora centre over a 2 weeks ago to go and purchase some clothes for my children. As I entered I went to the girl section first to browse and went between the shelves, the manager was laying against the wall and I had to squeeze myself between her and the shelf and my shirt got stuck on the shelf and ripped. She immediately stood up straight and walked away. I then walked on and then got really mad as the rip was big. I then went to her asking her to speak to the manager and she told me she is the manager. I then said to her that I'm not happy and she told me in a very rude manner to report it to the head office. I then showed her the shelf did not have its plastic cover on and this is the reason my shirt got caught. I do have photos of this. She was arrogant and kept rolling her eyes at me. I then said I will not phone anyone they can phone me as this was not my fault and she took my number after I forced her to. Till today no one has phoned me and I'm left with a piece of clothing ruined and a very bad experience of this specific PEP. The manager should be ashamed as this is not the way a manager must act and treat people and certainly not lean and a looks like she is going to take a nap against a wall.
