MakeMyTrip India — Train Ticket Cancellation

I booked a train ticket using MMT .I got my ticket confirmation text from IRCTC .Due to some personal reasons I had to cancel my ticket. If I try to cancel my ticket through IRCTC it says since I booked from different website it won't allow me to cancel via IRCTC. In Make my trip app it does not show under my booking details .If I try to contact customer support they inform me that I have reached bus support and should contact train support team. When I select train support it will suggest to manage from MMT app and that app does not have my booking details .I already lost 300 rupees . I still could not find any details regarding my booking . Even on my previous train booking they will send booking details on the day of journey and update journey details under completed trips . So I don't see a way to cancel train tickets booked via MMT .
