SO DISHONEST!!!

I tried to change a size of an item which was delivered yesterday. needed a bigger size. only to be told no size available. fine... then chose a different item which is more expensive and said I would pay the difference. THEN only to be told that the Burnt Points (B BUCKS) that i spent on my initial has fallen away and therefore lost. So any order you do with them in which you use their point system just falls away when you exchange or return. the lady I called today said thats how it is and dont worry you will earn on the new item...obviously not the same. NOW I AM SITTING WITH ITEMS THAT DO NOT FIT AND WHICH WEREN'T CHEAP AT ALL. ITS RIDICULOUS
