Myntra.com — I am complaining about my refund issue.

Address: Matri Niwas, Nigam Pally, Hakimpara, Siliguri., Darjeeling, West Bengal, 734001

I ordered a product with order id:[protected]-9637001 on 14th jan 2020, with successful payment through upi payment, id:[protected].
But i canceled the product on the 16th of jan 2020, regarding that i received the credit amount of ₹1688/- on 21st jan 2020, but on the same day, my money got debited from the bank account with transfer id: upi/rev/[protected].
Myntra says that the money is being transferred to the bank, but the bank says that they have not received any amount from myntra.
Myntra provided reference id:[protected]
What can i do now? Please look forward on my issue.
Thanks.
