Misleading and Poor Service - Poor attitude

I bought a printer in December 2015 which malfunctioned, I returned it back to the game store within the same month of purchase (December 2015) The product was returned back to me in the same month and was still malfunctioning. I returned it back to Game store in January 2016. I got no feedback so I visited Game in February 2016. The lady at customer services made phone calls only to find out that the product cannot be repaired. The supplier (Padmini at Canon) told the lady to credit me. I expressed my frustration for the inconvenience. The lady was proceeding to arrange my refund when she was stopped by the store manager as the manager said the refund policy is for products over \21 Working Days\" so I must wait to be refunded the next day!!!. I was extremely frustrated with that attitude and service and told the lady I would buy another printer from another store and not support game. They needed a day to get me the refund, so I went back to the store at the end of March 2016, gave them a month. but now being told that I cannot get a refund instead I must take another new printer?What must I do with it? I already bought a printer! My repair document states for me to be credited!"
