Booked a ticket form Australia to NZ during Covid, when Au & NZ had a bubble happening. It shut soon after we booked it and or flight got cancelled. We got the email saying that the refund is on its way. Fast forward 2 years later (!?) and we just got the money back. We had to engage the lawyer to be successful at it. Cost us around $400 in lawyer’s fees but we have received ALL of our money back - around $2900. Spending $ on the lawyer definitely worth it!
Do not bother calling them, they all say the same thing ‘we will escalate this case’ but nothing happens. They hope you will give up the money and so chasing them. Not me!!!
