This is definitely a scammer, if you value your dollar, keep away from this booking agency.
I booked the ticket from Sydney to Cairns, but due to COVID-19, the flight company cancelled the flight, then flyfar refused to give me refund, after many calls and arguments, they said give me open ticket voucher. But after a few months, when i try to use this voucher, they keep hang out my calls when i call them again and again. Their customer service is horrible, very rude communication. They just embezzle my money at all. Keep away from them!
