Worst flight / service on a flight to date...

Allow me to share what I've just emailed Jetstar: This was the worst international flight and service I and many others no doubt have experienced. Many on board said they would never fly with Jetstar again. Not only was it unexpectedly cancelled (not once, but twice) resulting in flying some three (3) days after my original flight should have, no real explanation or apology was given. This entire situation was made worse by 1) having to walk from the terminal to the plane at Narita in a storm resulting in being drenched by the time everyone had actually boarded - no umbrellas available, 2) a delay after boarding of more than an hour - a number of children were unable to use the toilet as the seat belt sign was on for this whole time, and 3) a huge line up to check in at Narita - far too few staff. Again, no apology for any of the above was forthcoming. The rumour is that Jetstar cancels flights at last notice which are not full. Could you confirm this? As a result of the back-up of 3 days' worth of cancellations, it was unsurprising that upon arriving at Gold Coast airport, processing time took two (2) hours. A 4000 yen travel voucher in compensation really is a joke.
