Jetstar's website problem became mine!

Below is the post I made to Jetstar's Facebook page- says it all!

Hi Jetstar, as per your rules I'm only stating facts here. Your website today 'encouraged' (your word) me to use Poli to pay for my booking for my flight tomorrow (Sunday). I did. When I hadn't received my itinerary I rang your call centre only to be told that my booking had been cancelled due to non-payment. My bank statement clearly shows you took the money out. According to my bank (thank you Kiwi bank for being awesome!) Poli doesn't process over the weekend and I shouldn't have been given the option to pay using this option given when I was booking. Again, my bank statement clearly shows you took the funds out ok, and even gives a reference number. I was told to just pay for another ticket and it'll get sorted out later. So I get to pay twice for a flight? Yaay! I saw people who missed the flight in Auckland because your people couldn't process them fast enough and the flight closed WHILE they were waiting in the queue - and they had been there in plenty of time for a normal check-in! I've rung 3 times today, my BANK rang once and even submitted the online billing application for me because he could do it easier than I could on my phone. He even sent you official bank confirmation the funds had cleared as well as my bank statement as per the instructions of your phone rep. Your rep said someone would get that info and call me straight back to sort it out. That was 9 hours and 2 phone calls ago, and still no progress. I'm stuck at the other end of the country because of YOUR website's error and you don't seem to care! Please respond- I've tried everything I can think of to get someone to help me there and apparently no-one seems to give a damn about providing even a small amount of customer service!
