Very Bad customer service

<p>We booked flights from Auckland to Sydney and Sydney to Johannesburg. The day before departure we went online just to find that our flight was moved to the following day.</p> <p>We made back to back flights from Johannesburg to Cape Town which we had to move on our own cost due to the delay.</p> <p>I send Qantas a request twice on their customer service website to send us a letter with reasons of delay which would be used to claim back from travel insurance.</p> <p>After a while I turned to their complaints department and send a mail without any response.</p> <p>To this day I have not received any feedback or response from Qantas.</p> <p>I am very frustrated and call after call has turned into nothing.</p> <p> </p>
