Refusal to exchange and Bad Attitude

On 23 April 2015 I returned 1 day old shoes at Woolworths Brooklyn and the Manager there refused to exchange and told me that at WOOLWORTHS THEY DON'T SELL SHOES FOR COMFORT. The only reason I buy shoes from Woolworths is because their shoes are confortable. Since they no longer sell confortable shoes what more reasons do I have to buy their shoes? Apparently they only exchange items that are in a wearable condition, exchange was refused without understanding a real reason why I brought back the shoes. I called Head Office and one guy told me to ask the store to call them back and when I returned I was assisted by another attitude Manager. They insisted that I use my cellphone again to call the head Office since they couldn't get hold of the person who was assisting me online.
