Travolook — Amount was debited but the flight ticket wasn't booked

Website: travolook.in

I had booked flight ticket through travolook on for 6th September from Ranchi to Chennai. The ticket wasn't booked due to their problem but the amount of Rs 3509 was debited. They sent me a mail saying that I will get the refund within 10 to 15 days. It's been more than a month and my amount is refunded. Kindly get it refunded. Below is the mail they sent me:-
