Great but lost my money

I dont see anyone else having this problem so please dont take this particular rate to heart; its a great and fun game, well developed and intuitive, however when I bought the Knight and Archer skin I used them once and when I came back to the game they were gone and its saying I need to pay for them again. A refund or return would be appreciated.
