MakeMyTrip India — Unable to transfer the refund money to original payment mode

Dear Sir,

I have scheduled my trip from tiruchirapalli to sharjah on 30th March but due to some reason the flight travel date is rescheduled. Then I approached the customer care for refund and it is done in MMT wallet.
This is to inform you that am unable to transfer the refund amount to original payment mode. The money is in my MMT wallet. There is no option displaying to transfer to original payment mode. Kindly help
Thank you
