MakeMyTrip India — Booking cancelation refund

I have cancelled my one trip on 28th april 2023 and i supposed to get Rs. 6162 for that cancelation. My Booking ID is NN7F7DDIZV5IIC4U9507. Its being 12 days and i have not received anything. I have also contacted many times for this and also provided all my details like bank statements but still not received anything yet.
They also asked me to connect with bank with the RRN number provided by the MMT. I spoke to the bank and they told me to ask MMT to visit the any bank branch with the transection and UTR number. I informed the same on 3rd May 2023. but still my issue is not resolved.
They are not listening anything now and one of their agent named sourav instead of resolviong my issue he is saying this is not an issue.
Kindly help me to get my refund back.
