Myntra.com — amount has been debited but the order is not placed also did not receive refund

Address: Sushmita women's hostel jayabheri pine valley, Gachibowli Hyderabad, Hyderabad, Andhra Pradesh, 500032

Today on 28 dec while placing order the amount was debited from my bank account but the order is not place. I called to myntra customer support they informed that they do not have clarity on any transaction, your order is cancelled and your payment is stuck on gateway. I have received mail from my bank that the payment has been done to myntra mentioning the transaction id and the invoice number. Still myntra is not refunding my amount.. If we have not paid then how my bank generated the transaction id.. Highly disappointed!!!
