Air Asia — Refund related

Dear sir,
Earlier on 23.07.2020 i booked a ticket from air asia mumbai to kolkata of rs 5286 (Pnr no:y696jq). Due to corona the flight was cancelled and on 02.08.2020 i received a message of getting refund of 1135 rs out of 5286 rs. I could not understand why a huge amounts were deducted as i have not cancel the flight. It actually was cancelled by the airline department. I want to know the reason behind a huge amount deducted. As i request u to look after it and deposit my full refund amount as soon as possible.
