Travolook — Refund Not Made yet

I booked flight from Travolook (Ahmedabad to Chennai). Amount deducted but booking get cancelled due to some technical problem from their side, they agreed. I called customer care for refund they said that I will receive my refund within 10 to 15 working days. After 15 working days I called them many times, they were simply saying you will received your amount tomorrow or within two days every time, BUT still I haven't received my amount.

Strict action should be taken. So that they will not be delay in future to the customers.
