@rafanaldo7, You should include the screenshot of your conversation with their email support in the main post. You may also include the deposit email notifications as "proof of payment". Winz.io sends email notifications on each deposit. Anyway, I just checked your complaint on Casino Guru. Winz.io representative has replied there yesterday. Judging from their statement, you aren't going to receive the winnings from them, no matter what step you take now. They have already refunded your deposits. Winz.io representative has mentioned this clause of their terms:
2. CHANGES TO TERMS AND CONDITIONS
The Casino reserves the right to unilaterally change these Terms and Conditions when such need occurs. We will do our best to notify our players of any significant changes by email. However, we do recommend all players to revisit this page regularly and check for possible changes.
Have you received any email from them in the recent months about the change of their terms? Winz.io team is partially responsible for this inconvenience if they haven't notified you about this before confiscating your profits.
