Cex - I will never ever set foot in that shop again

Today my daughter upgraded to an Iphone 5 S. The phone was out of battery so had a brief look. BIG MISTAKE !! Bought the phone and returned home. My daughter then noticed not one but two cracks across the screen. As soon as I could I brought her back to the shop which was within 3 hours of purchasing it. They said she must have cracked it twice in the 3 hours !! I was told to leave the shop or they would call the guards!!
