I booked flights with ANA around ~4 hours ago via Concur Travel, and finished the booking, emailed myself in the itinerary and saw it show up in my ANA account. Then I checked the trip again a few minutes ago and saw all the flight status changed to "Cancellation Confirmed". I did not trigger any cancellation from my part, and no notification email show up as well, it's only when I open the booking in Concur that I found out. I checked my reservation on ANA's website again, and it's also cancelled there. What do I do now? Should I rebook my flights? The ticket is also a non-refundable ticket, I think, so I don't know what will happen to the charge....
