Airasia — 33 percent Refund only and that too in airasia credits

Booked tickets for 3 adults paying 10953 but due to covid passengers couldn't travel. Got 3366 rupees in airasia credit to be used within two years. If in airasia credits then least they can do is refund full amount in credits or credit my bank account with 33 percent. By keeping my money as airasia credits what do i benefit - nothing. No reponse on contacting the airasia by mail.
