I applied for a Challenge VA Platinum to Qantas Gold last November with some flights to Europe coming up and provided the full 12 months set of documents. Got asked to become FF member first which I did and booked/flew in December. Then, after some weeks I got asked to resend the documentation again and eventually got offered the Challenge 3rd January asking me for the preferred Start date. Since then I did not have any success to get the start date set. Trie by mail, chat and calls since today when I got eventually told it cannot be backdated to December even when I applied in November, Quantas lost Documents and took a month to eventually decide.
To me, Qantas sucks at least when it comes to support. Never got any issues with VA support. What a really disappointing difference :-\
