ASDA Store Assistant interview questions

The Interview was easy and straight forward they had myself and another candidate replenish stock with help from another member of staff, who asked us some questions like Why ASDA?, What did you do before? They said they would contact me the day after the interview and it wasnt until the day after the day the specified I heard from them, so I asked them what the delay was and they didn't give me a straight answer and told me to wait until they chased up the person who should have contacted me, but over the weekend I got and Email saying they didn't want to process my application further. Which I found disrespectful as I had asked them a simple question politely.
