Nykaa.com — order not placed but amount got debited

Tried to purchase 4 products nykaa mob app on 5th march. Have made payment through axis bank netbanking. And payment was done and amount was debited frm my account.. N i also have my axis bank transaction ref no... But still the order has not been placed.. No order no or no order details r appearing in the nyka acc.. They have send no msges or emails regarding the order placement.. So am pretty sure that order has not been placed.. All the items r still in my cart... I want u to refund my amount or place the order again...
