Long Long Day

Planned and paid for Jetstar flights to Perth from Melbourne back in January 2017, all good.
Move onto early September had to change one ticket to fly back at later date, upshot forfeit original ticket had to buy new ticket to come back, okay can understand it was a cheap ticket to begin with. Flight was changed from being direct to Perth it became a stop over for 5 hours in Adelaide, had to alter accomodation, hire car at our cost they did offer to cancel flight orginally. Tried for three days to web check hubby on line could not do, kept telling me internal error, they promised to fix that with their IT department never did, okay thats ok check him in at airport. Same again when leaving Adelaide all good we arrive in Perth late but arrive. Holdiay is going well hubby flies back home without a hitch, meanwhile I enjoy my break. Time comes for me to leave out to dinner last night of holiday when I get message that my flight which was due to fly in 5 hours has been cancelled, so far this one flight has cost me $462-00 only one way with Jetstar. Only two options available fly next day at 2pm direct to Melb or that night at 12-05am with Sydney lay over for 2 hours as I was supposed to work that Monday night I chose the 12-05am flight also the Monday direct flight was totally booked whithin half hour of cancellation notice. After delay without any explaination except flight running late we left at 2-10am. Great we arrive at Sydney airport not knowing about the radar trouble I had been pre boardered from Perth airport so when I went to check in they told me that they had me on the wrong flight, my flight would be leaving at 10-10am and not 8-25am. Without notice that flight was cancelled, next they had me on another flight that was also cancelled I was was on three fliights that were cancelled. Other passengers told me of cancellations not staff. Get into Melbourne at 6pm been at airport in Sydney since 7-20am no sleep since Sunday morning. Not happy Jan. I know staff were doing their best I have flown with Jetstar many times and have also been ripped off by their luggage escapades but now my love of jetstar is well and truly over, over priced in money and time holiday due to Jetstar changes. Ps didn't make it to work either
