Welcome to the ICO world. It sucks I know. I've been denied payments a couple of times already. Hard to tell which one of the new ICOs is a scam ICO and which one is not, but there are quite a few. Good luck in claiming your reward.
P.S. Forgot to mention that you can report all scam ICOs in the Scam accusations board (provided that you have some proof):
