Note: We have just launched the no deposit bonus feature and are still testing it. This may lead to temporary delays in withdrawals, however these delays will not affect customers who registered before 19 December. Withdrawals will be made no later than Monday.
What is the bonus amount? Isn't there any kind of wagering requirement with the bonus fund? You have to deal with a lot of abusers who will try to take the benefit of the 'no deposit bonus' by creating multiple accounts. Withdrawal delays are reasonable for this reason.
BTW, there is a login authentication link at the footer of the website, where the hypertext says "footer.links_auth". Maybe the developer has forgotten to update the hypertext there.

The hypertext should be 'login' as the hyperlink redirecting to the login page. You won't see the above text in footer if you are logged in to your account.
