Before they had their new points structure, I had 2012 points and could redeem 1800 points for a $50 Isetan voucher. But now, without informing consumers, they changed the structure, making it seem as though we'll have more points, but in fact, raised the redemption benchmark.
Now even after paying more than $900 for air tickets, I have only 10985 points! Oh wait, isn't that much more than before? But hey, how many points do I need to redeem for that voucher? 10980!
So now I get more points but redeem less. You do the maths.
