Website:

Flight booking website

I booked a flight from travolook website on 25 oct and I received an email saying your booking has been cancelled due to operational reason and money will be initiated within 10 to 25 working days excluding holidays. It been more than 3 months now I haven't received my refund yet every time I call on their helpline no. They say you refund has been failed from merchants end and it will take 5 to 7 days more. But I didn't received my refund yet Please take strict action against them.
