Rude staff at Edgars TygerValley

I visited the Tygervalley shopping centre Edgars recently and was looking for a very particular clothing item. I asked a store assistant if they had any stock, she immediately said no. I then proceeded to leave the store, but on my way out I saw a whole array of these clothing items, even finding the perfect one. On my way to the fitting room to try it on, I told the store assistant that the store in fact has MANY options of what she just told me they had none of. She just gave me a look, rolled her eyes and turned away. I was really shocked at this disgusting service as I had not purchased from Edgars in quite some time and now this was the 'welcome back' that I received. Staff like this need to be disciplined as they are going to chase customers away
