Frustration to the max

I was all ready to get on my flight to Perth, the screens had shown no delay at all. Then suddenly it changed to an hour delay. That was fine, I could handle an hour delay. Then the plane has an oil leak, so all of the passengers were disembarked off the plane. No answers were then given and since they could not give me a time as to when they would be leaving or an approximate I walked around Adelaide airport to find a Jetstar staff member to ask. I could not find anyone. I was eventually told if I did not want to continue the flight, which I honestly did not, I felt uncomfortable that they fixed an 'oil leak' in an hour and did not want to risk it. I still could not find any Jetstar staff to talk to about this issue. I eventually asked a woman behind the gate desk what to do and she told me she would put a note on the booking that I did not fly and to apply for a refund. I then called Jetstar today, to be told I should have sorted that out at the airport. Was he kidding? There was NO staff to talk to AT ALL. I am disgusted by the way the call centre operator talked to me, also not being able to give me a reference number to ensure my refund would be going through, but also the way the terminal staff handled the issue. The flight attendant was acting so dumb when I was trying to get an answer. Definitely not flying Jetstar again after all of this.
