MakeMyTrip India — Mycash wallet

I cancelled a booking with MMT and Rs 4258 got refund into mycash wallet of mmt.
I tried to transfer the same from mycash wallet to orignal payment mode which is axis band credit card.
The amount got deducted from mycahs wallet buy didnt reach my card. and i got below sms from MMT:-
Dear *Ankit*, we were not able to refund *₹* *4258.0* My Cash to your original pay mode. Our customer support team will shortly get in touch with you and help you with getting your money back.

Now it has been 22 days i am trying calling and reaching mmt they are not refunding my money. Instead after every call they raise a new complaint and close it after sometime.
I want to file a complaint regarding them. Please help me to get mu refund back.
