bad customer service

I went to exchange a kettle which I bought last June as it was not switching on,the lady confirmed that it was not switching on and went to ask the manager if she should refund it as the cord was slightly burnt and the manager refused. I asked to speak to him and they showed me his office, I went and explain to him but he never bothered to listen to me nor look at me. I felt insulted and never going to shop there. <br> Hi
