Edgar's selling ****s

On the 30th of June I brought Levi's jeans at Edgar's promenade.within 6 month's the Jean was already damaged,so I returned the Jean at Edgar's in waterfront.the store manager came to me and said they won't take it back.how?because I brought quality,this has shown me that at Edgar's stores they are selling ****s to customers.why it's damaged if it's good quality and refuse to take it.i won't buy any of their ****s ever again.
