EaseMyTrip.com — Flight cancelled without my permission and they didn't gave full refund

My booking ID is EMT69956511
I had booked ticket of date 6th April 2020, due to lockdown airline cancelled flight and gave me open ticket (I have physical copy from Airindia).
But when i went to reschedule my flight Airindia told that Easemytrip has already cancelled this flight and we refunded the full ticket amount on May-2020.
So Easemytrip cancelled my open ticket and didnt even informed me about this, they kept booking amount for almost 1 year and didnt informed me.
Now when I asked for refund they deducted convenience fees + Airline
Cancellation Charges + Cancellation Service Fees. while DGCA has already passed rule that there will be full refund.
This is a fraud which Easemytrip is doing.
