Refusal for exchange and bad customer service

<p>On Sunday 2016-10-23 i bought some items on sale and when I got home they did not fit. On 2016-10-25 I went back to the store to return them. Their till point were faulty so their kept on calling the manager who eventually got feed up and as she is too busy to be called time and again. The manager had a terrible attitude and she was complaining as if she was doing me a favour. </p> <p> </p> <p>I eventually got the shock of my life when they told me they don't take back items on sale back. They have a 30 day refund/exchange policy so I do not understand. Please Help!!!!!!</p>
