Game not taking responsibility for faulty products they sell.

I bought a Trojan glide 500 from Game stores Cresta that is faulty. When I returned the product that is still under warranty I was told that I must contact Trojan to repair it myself. I loaded the big glider back into my vehicle and proceeded to contact Trojan. This was on the 10th of June. Since I contacted Trojan and send everything they requested I have not heard back from them at all. I do feel that because I bought the product from Game and have the original receipt, and because it's still under warranty, Game is responsible for the repair or replacement of the product. My commitment was with them and I feel that they need to step up and take responsibility for the product they sold me. I did do as they asked and contacted Trojan on my own cost and time, but nothing has come from that and 11 days later I am no closer to a working exercise machine than I was on the day that I went through all the trouble of loading it into my car and reload it again, and took the repair process on myself like they instructed me to do.
