Terrible , worst customer experience has cost us thousands

Not even sure where to start , had two flights delayed from Bali to Melbourne. The first was for "operational reasons" from looking into it I just think they were trying to squeeze in an extra flight, we never got an explanation. . We have two young children so the "alternative" flights they offered for the first delay getting in at 4am in the morning didn't work . When we tried booking the next day they were full. We asked about the following day they said we could but we would have to pay an extra $2100 as it didn't fit in their recovery period!! (is it our fault your flight was full). After about 4 hours on the last day of our holiday on live chat which was pointless and trying to contact Jet star from Bali we gave up. Had no choice but decided to make the most of it and extend our holiday. Ended up canceling and re booking flights a few days later at a significant cost . The second flight also ended up being delayed by 20 hours (changing a further 3 times) due to technical issues .Jet star offered to pay for accommodation and a meal allowance for the 4 of us up to at total of of US $700 (150 passenger accom and $30 for food) Our total for all of us was $400 I have receipts etc but have so far been offered reimbursement of of US $250 . Emailed twice no response and spent about 2 hours on live chat getting nowhere and making me feel like I am the one in the wrong. . Good on ya Jet star for living up to your reputation as the worst airline in the world. Never fly these clowns it has cost me thousands and wasted about 12 hours of my life. Why should my insurance company have to pay for numerous errors on behalf of this company!!
