Poor quality stil

Mr price gateway actually don't deserve even a single star. Bought sneakers from them on the 28th if not 27th of October mind you it's not even a full month and a stitch opened. Lost the receipt cox I as I was happy with my purchase now this... They refused to give me a new one saying it says all over the store that I can't return without a receipt. When shopping I take what I want not read every nonsense
