Haven't even flown, and customer service is already appalling

Jetstar's customer service is beyond a joke. I just had a friend spend over an hour in regards to her flight to visit her terminally ill father. Absolutely disgusted with Jetstar's management. She received a text confirmation only to find out 2 days prior that they never received payment. In a "recorded message" to customer service their representative admitted that this was a Jetstar system error and she was never given the opportunity to rectify the mistake Jetstar had made. Let me reiterate here, this was an ADMITTED Jetstar mistake, where Jetstar's customer representative also admitted that a manager did not want to discuss this issue with her because they did not want to deal with the issue. Jetstar's best solution for their error was to offer her flights at a drastically higher price, which she had no choice but to pay. Absolutely disgusting.
