I re-qualified for points club earlier this membership year but never received my hotel voucher in my emails. They said you need to be subscribed to their "Exclusive offers for Qantas Frequent Flyer Members" in your email settings (such a dumb requirement by the way), and I swear I had that selected as I got the vouchers last year via email - but when I went to check it was unselected.
I quickly fixed that, then refreshed the page and double checked it was selected which it was in case it would get re-sent after a period of time. Then a week later I checked it again and "Exclusive offers for Qantas Frequent Flyer Members" was unselected yet again. Serious website issues going on under the hood here. >.>
Anyways I messaged Qantas FF support and they just cited I needed to have that option selected in my preferences and then happily stated the code to use - but it was the exact same hotel voucher code from last year - which I had already redeemed - So frustrating! Still waiting on a reply from them about it.
