EaseMyTrip.com — Not getting full refund for flight cancellation from airlines side.

I booked a flight on Sep 3, 2024, from Easemytrip.com. The flight was booked from Ayodhya to Dehradun for the date 16th October 2024 in Alliance Airlines for two passengers. The total fare was Rs. 8248/-.
Now, on 25th Sep, I received an email as well as SMS on my phone number which stated that the airlines have cancelled my booking. On the message and email, they stated that the passenger can claim full refund or schedule for another date. I want a full refund because rescheduling is not an option for me right now.
I spoke with Alliance airlines customer support and they said that I need to contact EaseMyTrip customer support for the refund matter. When I spoke with EaseMyTrip customer support, they said that I will be charged a cancellation fee. The agent guided me to go to my bookings, click on cancel the flight and choose "airlines cancelled my flight" option. When I did that, I found out that the total refund amount is coming as Rs. 648/- only. Seriously!!!????
How can an airlines, who itself cancelled its passengers flight and now charging almost 90% of the total amount????
I just want my full refund, because I wanted to go on the same date and I did not cancel the flights.
Kindly help me in this matter.
