Baggage Inconvenience

I am very disappointed by the level of customer service shown at the Jetstar check-in counters at Perth T4 Domestic Terminal. On Monday night, my flight was scheduled to depart for Sydney at 10:45pm. I had already checked-in online and received my SMS boarding pass in advance. I arrived at the airport at 10pm and proceeded to the automated check-in counters to be printed an official boarding pass and check-in my luggage. Due to a failure in the automated system, I was made to line up in a line where three other flights were checking in, being serviced by only three staff. By the time I reached a counter, I was told that the baggage drop had closed and that my luggage would not be sent to Sydney, and that I had to organise my own way of sending my luggage to Sydney. This is completely unacceptable considering I had arrived in time to check-in my luggage and paid for it! In addition, the automated check in counter displayed that my flight to Sydney was delayed by 30min and due to depart at 11:15pm instead of 10:45pm (I have evidence of this as I took photos of the automated machine). The lady that refused my luggage said her system did not show this delay. If perchance I had decided to go have a coffee, go to the toilet etc due to the displayed delay in the flight, I would have completely missed the flight. This has caused me much inconvenience with my luggage still stuck in Perth. I have never had such bad service by Jetstar. If this matter is not sorted to my satisfaction, I will not fly Jetstar again!
