Myntra.com — payment refund

I was placing an order and something happened my order wasn't placed yet my payment of 1088 got debited with txn id of 105633, and myntra is saying that they haven't received the payment even though my bank gave me the transaction id and said that the payment was made. I reached out to them and after 5 long days of wait they finally responded in a really unsatisfying manner, they simply wrote we haven't received the payment kindly contact your bank for further details, like really?, i have to go to the consumer court if the refund is not done.
