Via.com - Non refund of cancellation of airline ticket for more than 40 days

We cancelled the ticket with AirAsia PNR no. JTICHL on **nd March due to rising covid cases and necessary to carry RT-PCR test to Bangalore from Mumbai flight on **th March,****. Air Asia said they refunded the amount to travel agent Via.com and it will be done within * -* days.
After that we waited but never got any cancellation amount. We called Via.com many times following weeks. they always said it will be returned in *-* days. we also have email on constant follow-up dated **th March that money will be refunded in * days. different CSR of via.com always have different reasons. Low staff, covid excuse. But i think refund has to be processed once from their system and it is done by the systems . today ** April , we called again then they it is under process and need another *-* days .
this has tested our patience, I don't understand when we book , money goes to airline within * day from credit card but when we ask refund it has taken ** days and still waiting for money which will be given partly. I have low balance in my accounts. business is down due to covid and now this mental harassment by via.com to refund our hard earned money. We don't know how many people they are harassing to refund the money.
