Worst service at LV sandton city

On Tuesday 4 august I went into LV sandton city looking for a backpack, after about 10 minutes I had to ask for help because all the sales people were busy chatting to each other! This was obviously my first mistake because now the sales lady is clearly irritated with me, she went into the back for at least another 10 minutes to find a backpack & returned with nothing, I then asked if she would show me something online, she was clearly annoyed, she attempted to use the computer but after a few minutes of no success she suggested I look online myself later! She constantly rolled her eyes & when I asked her name she she even clicked her tongue at me! I then told her I had never before experienced such bad service at LV she said \sorry for any unconvinced caused"while glaring at me. When I asked to see the manager"
