Just to follow up on this, submitted the online contact form requesting a points refund yesterday afternoon, and had them restored earlier today (in case anyone like me was wondered what the go was).
Had a success on this evening’s QF1529 to Melbourne, although the original flight now seems to have been cancelled and replaced with a configuration without J.
Still says upgrade successful on the new flight though. That’s lovely and all, but I hope they give my points back!
Got one for 1400 points for spending $0.01 at Woolworths. Describes itself as a “top up”. I have 300 or so points currently so perhaps in some sense it is, wonder if that number would have been smaller if I currently had 1000 sitting there.
