Reward flight to Sydney

Hi All,
I've been a lurker here for a while, but have decided to jump onboard as I need some help!
Is it me or is the Flying Club|Rewards flight checker really misleading?
My partner and I have been carefully saving our points in order to book a reward flight from London to Sydney travelling out next Feb, coming back early March. I've been keeping an eye on the 'L' class flights until we had enough points to upgrade to PE. That day arrived today.
On the website it says 'Book your qualifying flight below and you will become eligible for an upgrade.'. 'L' is listed as a qualifying flight.
The website gives the impression that, all I need to do is book a qualifying flight and then I can upgrade. But for some reason, I decided to call the call centre. The call centre tells me there are no class 'U' flights available for the return leg in March - on any date!
But hang on I said, the online checker says there are class 'L' flights, it says there is PE space available - it says in bold 'Book your qualifying flight below'. Yes says the operator, but then you have to select your upgrade and you'll see that there are no class 'U' tickets.
So, I've returned to the online system, I've gone through the process again, but it doesn't make any mention of upgrading other than by spending further cash!
So, am I missing something here? Am I being really really stupid or is the website extremely (and maybe delibertely) misleading? Could you end up buying what you think is a qualify and eligible ticket only to be told you cannot upgrade? What happens then? Will they give you a full refund including the credit card fee?
Is it really the case that there is no option to upgrade the return leg of the journey on any date in March?
And finally, how will BA's WT+ compare? I'm rapidly falling out with VS and wondering if BA might be a better option - during the 4 day sale this weekend, I can get a better price on WT+ than Class 'K' PE. If I cannot by an upgradable ticket, then BA may be a better option. But I'd love to know what people think!
