MakeMyTrip India — Not refunding the Money

I have booked a ticket through Make my Trip from CCJ to SHJ Booking ID :NN[protected].
I was not able to travel due to covid 19 and have cancelled the ticket. As per Airlines the ticket was cancelled on 10th April 2020 and refunded to travel agent (make my trip) till date i did not get the refund.As per Make My trip a credit voucher is been issued but i have not received any credit voucher or any option in my MMT account to book another flight. I tried contacting MMT through email and telephone but not getting any support or response .
