Thanks everyone for your input and questions.
I've decided to pursue a credit card chargeback as a first course of action, as I was misled (most likely intentionally to quickly solve a problem and move to the next customer) by a Qantas representative - resulting in a transaction taking place without my knowledge or consent. By definition, this is theft.
Will post an update when it's hopefully resolved.
I hope this acts as a cautionary tale to anyone who may face a similar situation in future.
Hey everyone,
Merry Christmas and a Happy New Year full of airborne adventures.
I forgot to circle back to this - not to take a victory lap, but to encourage everyone facing a similar situation with Qantas (or any large corporation) to keep persisting when faced with constant denial, template CS responses and weeks between those responses - especially when the facts are in your favour. The below response came from Qantas Customer Care a full 4.5 months after I first raised the complaint:
"Thank you for your continued patience, and we sincerely apologise for the delay in addressing your concerns.
We fully acknowledge the distress and confusion caused by the circumstances surrounding your duplicate booking, and appreciate the detailed information you’ve provided.
Having reviewed your case, we acknowledge that the booking under reference [redacted] was created and charged to your Visa card without your clear authorisation at the time. We take full responsibility for the actions that led to this and are genuinely sorry for the inconvenience and frustration this has caused.
As a gesture of goodwill and by way of resolution, we will be arranging a full refund of [redacted] via Electronic Funds Transfer (EFT). This will be processed through a secure reimbursement platform via a link that will be provided to you shortly. Please note this is being offered as a one-time exception.
We appreciate your long-standing loyalty to Qantas and regret that this experience has fallen short of the service standards you rightly expect. If there’s anything further we can do to support you, please let us know."
I lost count of the number of CS representatives I spoke with or wrote to but want to give credit to the team members at Qantas who demonstrated genuine empathy and excellent service despite having their hands completely tied by a bureaucratic PR machine unwilling to admit its failures (see "goodwill" above)
Despite this most recent experience, I have more Q1 flights pre-booked with QF than ever. Stockholm syndrome or objective cost-benefit analysis I'm not sure, but Qantas will still come out ahead in the long-run.
