There was no available service and no refund was offered. The next service was the next day. If you read the ticket, it's fairly plain, just not publicized.
Just to drive home the point, good friends of the family, a husband and wife, had booked a flight with Jetstar to Sydney for a wedding. Unfortunately the husband died unexpectedly the week prior to the wedding so of course neither was able to attend. When the wife applied for a refund, Jetstar asked for proof of death before considering a refund for his ticket, but refused to refund hers as they insisted she could still use it at a future date. Obviously, she had no further need or desire to travel. No refund was forthcoming.
You may well say it's not true but experience and documentation says otherwise.
