Due to various refunds coming in, I now have a negative points balance on my Altitude Black Qantas Amex. I was already planning to cancel it, and I still am. Does anyone know what happens in this situation? Is Amex able to claw back the relevant number of points from Qantas? I can't see any other way that I can square things up, without spending a few thousand $ on the card, which I don't plan to do.
