MakeMyTrip India — Refund please

I am Anil Kumar. On the 12th of February 2021, I was booking two train tickets via MakeMyTrip app. I paid Rs. 54 through Google pay. Unfortunately the amount was deducted from my account but the tickets did not get generated neither did I get any confirmation of the same. I have the transaction details of the ticket fare that was deducted from my account.
On the same day I contacted the customer care executive of MakeMyTrip and they confirmed to me that the amount would be refunded by 72 hours. But to my dismay, I have not yet received any amount, moreover they are not receiving any of my calls.
