I have received same dress material twice for two different orders. I have asked to exchange the product on the same day of receival. Fed of calling customer care from 10 days which will b either busy whole day or nobody answers. If anybody picks the call other number call ask which is busy or will not pick up the call.
Mailed many times to the customer care with all details and the picture of the received product but they always ask clarification about the order.
