Bags lost for 8 days

Ours is a really long storey, so I'll keep it as short as I can. Basically, Jetstar lost our bags, they were not delivered to our hotel when they said they would, and we made repeat calls (from Thailand to I suspect the Phillipines via their call centre) to them asking where our bags were, each time they said they had no records of our luggage being lost. We went 8 days without any of our luggage, and have worked out that we are out of pocket for a total of $370. And we rounded down. There has been no apology, no explaination, and we have made repeated phonecalls since being back home, were we get told that someone will ring us within 2 weeks...guess what? Like our luggage, those calls have gone missing! We've been trying since early December 2010 to get a response...on our 4th phonecall we were given the international.claims@jetstar.com email address. Why did it take 4 phonecall to be given this??!! Anyway, sent all of our evidence in, and asked for reimbursement...nothing. They don't even acknowledge that they're looking into it! 8 days of our holiday without any of our belongings, and we only spent the bare minimum to get the essentials, only 3 sets of clothes each so we could wash & dry them, and basic toiletries! I'm so fed up, am thinking of taking them to VCAT to get reimbused. We have travelled with them with no problems many times, and I understand that mistakes happen...but the service we've received since is disgusting. I will now NEVER fly with them again.
