I ordered a biba kurta in question along with two other kurtas. I didn't receive the biba kurta i ordered but something entirely different. I posted an exchange request for the wrong kurta, it was picked up from my place without any exchange and information. I called up customer care four times explaining the whole situation asking to deliver the original kurta ordered or issue a refund but my claim was declined saying the kurta (Picked up from my place) is never received at the head office.in actual the pick up guy was not suppose to pick up the kurta but he did and lost/stole it. But the company doesn't take the ownership of the misconduct by its staff.

I want my money to be refunded.
