less than a month old but doesnt work

less than a month i went to the game store in Tygervalley and purchased a Logic fan worth R699, i assembled the fan myself and was working fine, after 3 weeks something inside the fan decided to fall off and the fan stopped working then & there. i tried searching for the purchase receipt but unfortunately i think i throw it away with the box. I fail to understand why Game stocks and sells us low quality products, either my money back or the gets replaced. now im fanless in this heat!<br> <br> Upset customer, <br> Simphiwe Tamba
