GAME GATEWAY - DISCOVERY GAZEBO

Been to Game Gateway 23/06 to return Discovery gazebo as clips are faulty and frame is rusted, barely used as it was kept in storage, this falls under camping and outdoor equipment in their store, was advised by 3 of their staff members this cannot but returned and they only can "do me a favour and replace the frame" I was further told to report quality to Discovery directly although purchased from Game. There are other gazebos in the return area, so Game knows quality is an issue but still stock item on their shop floor, this is a blatant rip of as they fully know the product will malfunction or deteriorate within 6 months but take our money non the less. Is there no quality test on products or customer complaints taken into consideration when continuing to stock low quality goods. All I got was another frame - which is going to rust again in a short space of time.
