Air Asia — Cancelled flights, no credit or refund

Again, I booked and paid for return flights from MNL to KBV for my fiance departing April 2 2022 returning April 30 2022. Those a**holes cancelled flights without warning, despite dozens of emails and complaints they still refuse to give me a refund or any credit. I want FULL refund as I NEVER want to deal with them ever again. Booking reference was V3EYNM and booking number was #74644603. All I ever get is automated no reply emails that never solve it, and further emails telling me the case is closed. I paid those a**holes $464.36 AUD ( I am Australian living in Thailand) on 7th February 2022. They cancelled flights almost immediately, and REFUSE to answer phones, repsond to emails or sort this out satisfactorily. PLEASE HELP.
