Active Reflex GPs smar****ch

My wife bought me a Active Reflex GPS smar****ch for my birthday middle of September and gave it to me on the 27th of September. I had it for a week then the strap broke. We took it to truworths in Sandton city on the 25 of October and they sent the watch in for repairs. I have had no response whatsoever from Truworths. The watch has been longer in for repairs than what I have had the it. We would like to be credited/refunded because we don't want the watch back and something happens again to it and it has to go in for repairs again and I am without a watch again for how long.
