MakeMyTrip India — No Refund for CAB cancellation

On 29th October 2021, I cancelled my Cab from Ambala to Agra which was confirmed for 5th Nov 2021 due to an emergency situation and I already paid Rs 8427 in advance while booking the cab.
While I was hoping for MMT to deduct some inconvenience or service charges or cancellation penalty and refund the money back, I saw that the whole amount of Rs 8427 was cancelled and it displayed no amount refundable.
Could you please help me in getting my refund back.
I cancelled the cab almost 6 days before. Deducting the whole amount in this case I don’t think its justifiable.
