Edgars did not want to replace

I bought Bradford shoes from edgars somewhere in November , I did not use the shoes after 12th of Dec till the 12 th of Jan 2015.On the 10/02/2015 i have discovered that the shoes are completely cracked on the sole completely open both shoes, i took it the same day to edgars and the manager on the floor responded he cant take it back as it was me that walked it like that , so he was telling me that i walked R400 shoes completely cracked open in 2 months ? He took me to his line manager she said she will contact the supplier to find out if there is any other quality issues and they took pictures of the shoes and floor manager told me that he will contact me the next day. I haven't heard from them since . It is as if they just said they will to get me to leave but i see that as very bad service from them.
