Air Asia — Not getting my refund

I had booked a flight in AirAsia, but they have canceled my flight and rescheduled it to a different timing without informing me. So I have canceled the ticket and asked for a refund. Till now they have not yet refunded my amount. As I booked through a travel agency, so travel agency is contacting them on a priority basis, but they are not giving any update till now.
It's been more than a week.
Such a worse service by Airasia. Below are the ticket details. Please I request you to please get my refund done ASAP on a priority basis. I really need the amount badly.
