Two out of two

Booked return flights in July for my son and I, Perth to Melbourne only to get a text 2 days before planned departure date that flight was cancelled. Called the contact number to be told there were no flights available on the travel date, I could fly a day later or earlier both causing me to be out of pocket. Thirty five minutes later on the mobile phone new flights are booked and I am informed that I can not alter these arrangements as I have already changed my original plans - yeah because you cancalled my flight - I understand the man said. Forward to 2 day before our return flight I get a text informing me our return flight has been cancelled, this time after a twenty minutes on the phone I could get a flight on the same day but 8 hours earlier. I am told a new itinerary will be sent and that I can not change these flights as I have already changed my travel plans -sound familiar! The night before our new flight still no itinerary so I call Jetstar to be on hold for 23 minutes and then be told that there will be no new itinerary and I turn up to the airport checking and say my name and all will be good. Thank god for Qantas.
Jetstar and I will never do business again
