Air Asia — Air Asia Refund not Processed

I Booked Air Asia Flight Ticket On 2nd April 2020 Via IRCTC With A Booking Number C75MGX. Flight Is Booked For 17th April 2020, Which Got Cancelled Due To COVID Lock Down Declared By Government. From Since I Am Following Almost Daily Via Website And It Takes 2-3 Hours To Connect And Then They Disconnect Phone. Very Disappointed As We Are A Senior Citizen And They Cheated Us And Not Refunding Our Hard Earned Money. Total Amount What We Paid Is Rs. 5758
