Reliance Trends — very poor quality

Sir, i had bought one kurtha from your kodungallur store a week before. I wore it yesterday for the first time and i was so shocked to see that its already torn out in two three places due to the poor stitching quality. Kindly advise what i can do in this situation. I don't have the bill with me now and the tag was also removed before wearing. I had purchased this on 9th september sunday.
