Ripped off by Jetstar

Booked a flight for my sister in law to come to Australia and then a change in her circumstances mean that her visa was cancelled. Despite over 6 weeks notice Jetstar is unwilling to give any refund on the purchase (we would have settled for a partial credit or voucher to use off a future flight). Now they will simply resell the seat to another patron and double their money. Good for them, terrible for the customer.

As a comparison Tiger Airways were operating the connecting flights and they had no issue providing a full refund when asked, no hassle or push back whatsoever. You know who will will fly from now on...
