MakeMyTrip India — Booking ID - NN[protected]Kozhikode to Abu Dhabi in Air India Express on 16th April 2020

Booking ID - NN[protected]
This complaint is in reference to the cancellation of a flight with subject booking ID, which I made for Kozhikode to Abu Dhabi in Air India Express on 16th April 2020 .Only mistake I did was I made the booking via Make My Trip.
This particular flight was cancelled due to Covid 19 Circumstances and I received email from the airlines that particular booking has been cancelled and the refund is transferred to the agency ( make My Trip).
I have the email with me.
I also received a notification from Make My Trip that I will be getting a credit voucher for the same amount to reschedule the travel to a future date ( I have taken the screenshot and kept for the record ) . Its been almost 10 months still I did not received a voucher, invoice or refund.

Kindly support . I attached the email from airlines and screenshot taken from Make my Trip App.I also attached the E ticket for the reference.
