Game not playing the game selling poor quality goods

I bought an Empisal over locker from Game. It has never worked properly and has been back three times. Each time it comes back EXACTLY the same as before. It simply does not stitch. The machine technician told me it is simply a very poor quality machine.

I asked for my money back and was told I can't get a refund. Does Game know about the Consumer Protection Act and why can I not return the item in terms of their own customer policy?
