I had an excellent Customer Service experience a week or so ago, also - through the telephone channel. Admittedly, it did take some persistence.
Had happened upon a good JASA, LAX to MEL. Something around 130K, so not quite the Classic rate but, with earned points and no additional taxes etc, it suited my needs at the time. Of course, all other flights in the same period were in the 800K plus category, so I moved quickly to take advantage of the offering.
Right through to the Confirmation screen of the booking - then Nothing!
Started over. Same outcome.
Several calls to QF in trying to establish whether the seats were still available or not, with varying responses. Eventually talked to a helpful operator, who told me that she could not complete the booking but she could cancel the stalled booking and release the seat back into the system. This, she did. Tried again for the same booking, on a different computer system. Same result.
Another two calls to QF but eventually I found another helpful operator who agreed to make the booking for me - after trying to persuade me to switch to a Classic Award, that is.
For a modest fee, the booking was made by the operator, on the 380. and with seat allocation in Emerald City.
Thank you, Qantas!
