No feed-back on complaint about faulty equipment

I bought a Ryobi Belt and Disc sander from GAME Kathu and the box was damaged. On assembling at home in Kuruman, I discovered some parts missing. Back to GAME and the manager on duty exchanged product with other one. Assembled and all looked fine. As soon as the machine was started. the horizontal disc moved to the one side of the rollers. This lead to the belt being stressed and I had to start the belt by hand. Took product back to GAME-Kathu and they could not supply another sander. I was informed that this machine could not be used on a daily basis by GAME personnel . This machine was only used to finish of jewelry boxes and small \superwood\" surfaces. I was offered a refund by the GAME manager which I accepted. I have sent my complaint to Ryobi to enquire about this product, but Ryobi remains quiet. I need this equipment and would really like to know what Ryobi 's view on this issue/equipment is. Please help."
