Worst experience at Edgars Bayside.

I am not happy at all with the treatment i received today at Edgars Bayside mall. I walked in at 16:45. I was told the leave the shop at 17:00 before i finished my shoping. One of the cashiers started shouting saying i must go pay the shop is clossed. I only managed to buy shoes and left everything.is it how you treat customers at Edgars bayside?
