Additionally I would like to add that your original deposits have been refunded and only the winnings have been confiscated.
Our decision on the matter is final.

How can I get my winnings?
You must wager a total of 35 times the sum of your deposit and bonus before you can withdraw your bonus and any accrued winnings. The maximum stake whilst playing with the first deposit bonus is €10. Using the gamble functionality offered in some games is not allowed whilst having an active bonus. You have to complete the wagering within 14 days after the Welcome bonus has been awarded. For example if you deposit €100, you will get a €100 bonus and you will receive a total amount of €200 on your account. You will be required to wager €200 x 35 = €7000 in the casino before you may cash out. To see your bonus and how much you need to wager go to “My profile” and click on “My bonuses” in the menu.
