Myntra.com — Money for refund not received

Purchased two kurtas for ₹425 and ₹449 abd then opted for refund as the size was very tight . As usual they took the products and initiated the refund for both the products on 19th May 2021. I have not received the refund yet, on talkin with Myntra customer care they said the refund has been initiated on their end so go and talk to the bank. When talked to the bank they said that Myntra has not initiated the refund. The bank from which the payment was done is Indian Overseas Bank
