JAL unilaterally cancelled a partner award weeks ago, but Qantas appeared not to notice for some time, and a few days ago advised me by email of a 'schedule change' (5minutes) and gave me the option to Cancel on-line.
As this flight was now redundant I happily clicked Cancel. Got the acknowledgement it was indeed Cancelled.
Also got the "Due to the increased volume of requests....." line. This was not a rev.`` booking, and all they need to do is refund QFF points, and fees and taxes. Still waiting.
At this point it has passed being a call centre matter to a back office thing to be actioned.
It appears that lack of staff is not confined to call centres.
