the ticket selling agent (in this case, QF) has very little to do with it when it comes to irrops, operational issues like this. While yes, it's frustrating that if one wanted to make changes to said ticket, the original agent is required to do it (in this case, QF) but that's standard policy. Someone commented up thread that it would be good if this sort of thing could go away - that the operating airline, for example, could take control of an agent issued booking if need be and pull them out of the loop - but that's a whole separate issue). This was not a cancel well ahead of departure where one may consider dealing with the issuing agent appropriate if JQ did not offer suitable options.. but since this was a last minute operational cancel you really were in the hands of JQ. QF couldn't really do much at that point anyway.
