Well, well, well! Finally after 18months and more customer service calls than I'd care to remember, two ACA interactions and some social media ranting! I finally got this:
Dear Benjamin,
Thank you for contacting Qantas Customer Care.
Please accept our apologies if your query was not resolved in a timely manner. We never intended to make things difficult for you. We are committed to resolving the Airline Customer Advocacy claim that you submitted in regard to your price promise claim.
Upon evaluation, we've determined that we're able to offer AUD 933.00 travel voucher to your price promise claim. You may use this voucher towards a Qantas fare with Qantas flight number (operated and marketed). Kindly let us know when to proceed.
I appreciate you taking the time to reach us again and I look forward to resolving this for you as soon as possible
Is it a refund, no, but I'll take it.
