First even was a few weeks back when booked via their App - because I am a Club JetStar member it over-wrote my name over the staff member I was booking for - took nearly an hour on the phone to get them to suck up the nearly $300 in charges.
Now go again - crashes half way through booking - rushing and I pick the wrong flight. Get onto their help before the email confirmation arrives - they charge $85 change fee and don't refund the fare difference as it is a cheaper flight. Offered a $50 voucher - whoop dee doo. So short sighted.
