Indian Bank — myntra refund not reflected

Website:

Myntra

Hello. I placed two orders on myntra and they have initiated the refund already. M y bank account does not reflect the money at all. It's not the first time this has happened. None of my refund ever gets credited back to my account. Myntra has refunded my amount with reference number. They are saying they can't help as the amount 690 and 646 has been successfully processed from their side. Indian bank is saying they can't help me out. Where is my money going. I am using indian bank account from past one and half year and i am really disappointed by the loss of money i am having. Please resolve my issue.
