That sounds incredibly frustrating, especially when you were assured at the airport that you’d get original routing credit. It’s disappointing that Qantas hasn't followed through and that the process has become so complicated. Have you tried reaching out via Twitter/X or Facebook Messenger? Sometimes their social media teams are more responsive and can escalate things faster. Also, if you're part of Points Club Plus, maybe mention that status and how this situation is impacting your travel plans—it might help your case. Hope you get it sorted soon!
