worst customer service not humane

I was notified 8pm the night before 6.20am flight from adelaide to melbourne on aug 9th 2015 via sms that my flight was cancelled , which was linked to my international flight same day to phuket. After 1hr wait on hold with jetstar i was told they could not get me on any flight that day even with other carrier and i had to make alternative arrangement to get to melbourne to board my 2.45pm flight from melbourne to phuket. In frustration and panic that my first carefully planned overseas holiday off 6 month wait was looking at not happening, massive expense, time off work, i desperately managed to find last minute flight with virgin at a cost of $480 for 2 people one way adel - melbourne. Once checked in at adelaide airport with virgin in morning i proceeded to jetstar office in adel and lodged complaint with them to be advised that jetstar found alternate flight with quantas around 1am that day but they advised my travel agent and not me, what the fuck, what agent 1am on sun would get mess. Why???? The idiots of organisation had my number and couldnt mess me. Anyway the moral of all this fucked up poor service shit plane they call airline, they have offered me $57.51 credit for 2 people and $100 good faith for my loss of $480 im out of pocket. JETSTAR you have failed and will pay , i promise you im worst then a spreading virus and will make this a major announcement and tarnish your reputation. I know they are cheap flights but they are only good to transport convicts and animals not humans, cause there staff on plane are rude, shit seats, no meals unless you pay buckets, no water unless you beg . WORST plane carrier ever been in and thats 3 experiences , always same bullshit
