Dissapointed

I purchased shoes on the 13/05/2015 at 17:03 I fitted them in store but as you know you don't walk all around the store in order to feel if the shoes are really comfortable. I took the shoes home and next morning I tried to wear them, as I was walking out of the house I could feel that something was not right and I went back and took them off and put them in a plastic back and I returned them back to get a bigger size since its felt like its a small cut. I didn't even walk 20m it was far less than that, when I got to Woolworths they refused to take the shoes back and it wasn't even 24hrs of purchase they told me that the shoes were damaged and I told them that it could be a quality problem because there is no way I could wear a shoe less than 20m and it becomes so badly damaged that I'm unable to return and swop it for a bigger size.
