I have ordered women white truffle collection loafers of size 3(U K Size) and of cost Rs 1119/-. But I have received wrong product consisting of bellies of size7(U K Size). I have made a return request on the same day and got a message for pick up on next day but delivery person refuse to accept the product as he got the message from the company regarding the declining of the request. I have made several calls to customer care but they said they can't do anything as the request has been declined. This is the worst experience I have I have ever got from any shopping site. As my whole money gone in vain as the product received is of no use to me.
