Travolook — Not yet received the refund

I had booked my flight from bombay to goa on 20th dec but it got cancelled and they told that I'll receiv the payment within 10 to 15 working days.. Even after waiting for 10-15 working days they didn't refund.. I tried calling them several times but their answer was it's in process and within a week you'll receive the money it's been 3 months and I still haven't received the payment please take a strict action towards them and inform them to refund my money at earliest
