Air Asia — flight cancelled and then rescheduled without notice - need credit shell or refund immediately

Address: Mumbai

The airlines cancelled my families flight for 22nd june 2020 on friday the 19th june 2020 and said to apply for a refund or credit shell, then suddenly in the night of 20th june 2020 they said please ignore previous message your flight is reinstated. By then i had already booked another flight from indigo. Calling the airline multiple time but no response from their customer care and no response from the chat bot ava. I either need a refund or a credit shell for the loss incurred because of the airline.
