refusal to return my damaged item

I purchased a pair of levis on 1/09/2015 from the chatsworth store and a few weeks later the loop cut.when I went to the store the lady ashnee tells me that this has not happened before because I told her I am not taking the Same thing when she asked. I had a problem with a pair of shoes that I purchased from this store as well and because she remembered that I was the same customer she made it seem as if I am intentionally damaging the items giving me so much of attitude .I spend a lot of money at these stores and don't expect to get this **** i know my rights as a customer and cannot understand why the staff belittle the customers this is pathetic I called the area manager and was told he would call me back but that has not happened it seems as if this group does not valur there customers its really pathetic
