One the worst flight booking website. I've called them regarding the refund for the ticket which was cancelled on Dec 25 and still they are saying it's under processing. The airlines have agreed to provide with the refund and asked the booking agent to contact them when I contacted the airlines directly.but the flightnetwork is not following up the case nor replying to the emails I've sent even if they reply they say that booking id you've provided is not correct and if you reply to that email they will say to create a new ticket which will take another few months to get a reply. so pathetic booking service.
