Levi's India — defective jeans

I bought a black pair of levi's jeans from one of your stores and i spent around rs.2200/- for the same and i was confident with the product as i am using levi's since my childhood but this time to my utter shock, after using for the second time, i don't know how the jeans got torned off from near the back pocket and i want to tell that my jeans is unwashed. This is purely a matter of bad quality which has been provided to me with a company of repute called levi's worldwide.
This is my request to you to kindly change my product as per your policy so that i may not loose faith on the company.

Thanks
