I want to return the tshirt. first myntra says in 3-4 days tshirt will pick up but after 5 days myntra says tshirt is not return. after that i call the customer care but they also said tshirt will not return so that time i asked why that time he is not able to get perfect ans. and tshirt is new, but i received defective product, myntra executive said tshirt is perfect but my question is how can they said tshirt is perfect. however they didnt come for check so how can they know. due to this i face the dificulty so its my humble request to take action against myntra website.
