NO REFUND OR EXCHANGE FOR BROKEN SHOES

I bought a pair of shoes for R160, from the Westwood Store on 17/12/2015, I wore it for less than an hour and it broke, Winnie from the store had changed it on the 18/12/2015 & that also broken within 30mins. I called immediately & notified Winnie, not only did it break but the front of both pairs opened...I returned with the shoe on 21st, Winnie asked me to leave & she will contact me the next day but the problem is that I'm from Phoenix & could not come back to Westwood. After Winnie contacted the owner she notified me that I will not get a refund or exchange because she had already changed two pairs & that I bought it at my own risk. The broken shoes are at your store. I have bought 90% of my shoes from this store & have never had an issue... I would like ur immediate response on a forward before I contact HelloPeter & ECR consumer watch. Note that I cannot inconvinence myself with going back to Westwood
