Mytrip.com complaint: Still waiting on a refund

I booked domestic flights in Australia with MyTrip.com. The flights were cancelled by the airline due to COVID lockdown restrictions. I provided a letter from Qantas and screenshots of the cancelled flight to MyTrip.com. I asked for a refund NOT credit due to moving overseas and not being able to book further Qantas flights. I am now 12 weeks into waiting on a refund. I have called MyTrip.com numerous times, including 4 times today. I have asked to talk to a manager and each time I placed on hold and then redirected to an answering machine! I have had no call backs and no resolution. Qantas has ed they cancelled the flight and it’s now up to MyTrip.com to pay me my money back. I WILL NEVER BOOK or TRUST this company again. They are continuing to ILLEGALLY hold my money and NO ONE will answer my enquires. MyTrip.com are refusing to adhere to Australian consumer law and have provided no support.
