GoAir — Flight cancelled and money not refunded

Hi,
I had booked a GoAir flight from makemytrip app and the booking ID is (NF[protected]). Please note that amount of ₹ 6495/- was deducted from my Makemytrip wallet.

Flight was cancelled and till now the money is not refunded to wallet. Makemytrip is harrassing me to contact GoAir and GoAir is asking me to contact Makemytrip. Makemytrip is giving vague reply that GoAir will create a credit shell but is refusing to give further details on how to access the credit shell.

I request on this forum to please help me get justice since 6495/- is not a small amount and Makemytrip must refund the money to wallet as I was using their own wallet. Please help
