Nykaa.com — return/refund

Nykaa has a very disastrous customer care service. They fails to even respond to the numerous requests i have sent for the return of an item. A system generated response is all i get when i email them, promising to get back to me in 24 hours but they never do. If it were amazon or flipkart then returns could be sent easily and the amount refunded in under a week but nykaa does not care or even acknowledge customer's issues. Very pathetic service.
