Make My Trip - Not received refund against cancelled flight booking

I booked a flight to Berlin on **-**-**** through Make My Trip with Booking ID as NN*************. The booking was cancelled due to COVID-** pandemic and my refund was under process. I tried to contact MMT several times but could not their customer care is not responding and also they are not answering any email. I have sent number of emails to them and also posted a google review but till date I have not received my refund.
On **-**-****, I also contacted my airline through phone,i.e. Qatar Airways, about my booking and after checking my booking details, one of their executive,Mr. Bargav,has confirmed me that Qatar Airways had already refunded my entire amount and I need to contact the travel agent which is Make My Trip to confirm about the refund against my booking. Whereas MMT is just reflecting a message in that "The airline has assured that your booking amount is safe which can be used for a new booking with same airline, subject to paying any additional extra fare for the new travel dates and such other terms and conditions as may be prescribed by the airline" which is not true since the airline has already refunded my amount to the travel agent due to which my booking details is not stored in their portal and I have also received an email communication from the airline.
More than * months have already passed but I am still struggling for my refund as MMT is not reverting to any of my query.
Please support as I am worried about my total amount paid for my booking.
