Myntra.com — payment debited through airtel app and order have not placed by myntra

I was trying to place an order with myntra.com through their app on 7th april 2019. And i made a payment of 1070 through airtel money wallet ([protected]). Due to some problem i dont know why but money got debited from my account but no order was placed with myntra. Myntra denies having received the money but my payment has been made. Haven't received any confirmation of refund from myntra side even though i keep calling their customer care. This is totally disgusting... When i placed order there was an offer of some cashback from myntra if i make payment through airtel app.. I have attached screenshot of payment details. But money is yet to be refunded.
