Myntra.com — bank debited the money and now myntra saying they did not received my money

Its 100% sure this problem happened from Myntra.com.On 15th April I ordered a dress and I got a message saying "Order is unsuccessful " But Money was debited from my bank account. From 15th To 20, I called them 4-5 times and they first promised it was an error from their side and they will refund it. Yesterday I got mail from saying,

"We would like to inform you that the order was unsuccessful and we have not received the payment for the same. Please contact your bank support team for further assistance. Apologies for the inconvenience caused."
