I don't think there is a way of doing this, there is an impenetrable barrier that is put in place (for good reason) to prevent direct contact between customers and "executive" agents . This is the case with many airlines, it is very difficult to get past initial customer service agents. And there is absolutely no chance of being able to speak to some "high up" in Qantas about this, it is such a trivial issue, many customers have far far bigger complaints, on Qantas themselves - not Jetstar - and the "higher up" are won't engage either.
