First of all contact crypto-games's support.
If they don't respond then ask them in their ANN thread.
If still they don't reply or resolve your issue with your full satisfaction then start a scam accusation topic against the site.
Read the whole thread first mate, it is not that hard to read because there are less than 10 posts in this thread. If you have read it then you will not suggest it anymore as the issue was resolved.
For your reference:
They activated my account. 10/10 service.
As it is resolved, better to lock this thread to avoid spam like quoted above.
Edit: Or at least edit the title with something like [SOLVED].
