It ate my money as well. I went to buy some totems to craft some items and at first i hit the button and nothing happened, so i tried a few times and in the end it managed to register every time i hit the button and took the money each time but only once, the first time, did it actually refund the money, the next 6 or 7 it did not. Nothing appears on the transaction history of bought items.
Exactly the same thing happened to me!
