Three Diamonds and No Rewards

The Discovery vitality rewards page shows you all of these lovely rewards and it encourages you to save your rewards to get some of the bigger ticket items. However, now that I have three diamonds there are no rewards (well. a spa that is no where near me and an Incredible Connection voucher)! There is literally nothing for two diamonds either!

I am so disappointed because I have been saving my rewards and now I cannot spend them on the things I 'saved' up for. My diamond is expiring but when I called the help desk, they just tell me shame buy someone else a gift we can't help you.
