Travolook — Non receipt of refund

I have booked a flight ticket from Mumbai to Trivandrum on 19.12.2021 through Travolook and the same was cancelled from their side. They have sent a reply that, the refund will be credited to my account in 7 to 8 working days. Now it's more than 20-days, I have not received my refund inspite of sending repeated reminders and telephone calls.

Please take necessary action to get my refund at an early date.
