Levis — poor quality of sweater

This is to inform you that I have been a very kind customer of yours since years and this is the second time i am facing this issue of poor quality of my sweater which i have bought from one of your store. I went to one of your stores to get it replaced but I was told that I was not having bill of this item purchased . You only tell who will secure the bill of such item for months. This is just the trust of levis that I have been coming to your stores for shopping since years . Its not only I who has been purchasing these items from your stores but I have also referred to other customers also. You only decide what will be the image of yours if you will treat your customers like this. its around 1 year back I have purchased this item... sweater was around 2000 ...Its really frustrating that brand of such high customer satisfaction has such issues and beside this they are not resolving these issues.. Kindly either solve my problem or I'll have to knock the door of Consumer Court... I have been your kind customer for years .Kindly dont break your trust for few bucks. Kindly do the needful
