United Colors Of Benetton — jeans got loose at the first time itself

Hi there, i had bought a slim fit jeans from your kamla nagar, delhi outlet around 2 weeks back. The fit was so good that i did not try any other jeans was completely sure of it. I wore it for the first time yesterday for three hours and it got so loose and i kept pulling it up all the time. I was extremely uncomfortable and was embarrassed too. I never had such experience with ucb products. Please take it seriously. I would like to return this defected pair of jeans. You can reach me at 91-[protected].
