Levi's India — jeans

Address:

New Delhi, Delhi, 110059

I bought one skinny levi's jeans jeans in august 2017 from dwarka sector 7 levi's showroom. It got so loose now that i regret buying it.in fact within 3 months it got loose completely. I wasted 3k bucks on this #. It was for the first time i bought levi's jeans and now i regret.
I had blind trust on levi's seeing people's review but when i bought it for the first time it seemed excellent but with time it lost all it's quality and grace. I simply want now exchange or refund.
No levi's.
