damaged shoes that i could not return

i bought a pair of shoes on 7 October 2015 two weeks down the line my was damaged. i could not go to the store immediately to return the shoe. i was able to go to the store on 20 November 2015. The lady who was helping me phone customer service and Portia who was the person who was from their customer service told me that she wont be able to help me to replace the shoe. I then asked to talk to the manager of customer service whose name is Wendy who told me that she wont be able to exchange the shoe for me because I was suppose to return the shoe immediately. i am not happy with the way they treated me because my understanding is that if the shoe is damaged within 6 months it need to be replaced.
