Account closed and my money taken based on unproven accusations

Hello Askgamblers,

Yesterday I deposited 50€ with a bonus and played some slots and lost. I then deposited 1000€, and won 1300€ on blackjack after a few rounds. I then made a withdrawal of the full amount of 2300€.

The casino sent me an email today saying that they have closed my account and will not pay me my money. They are saying that I have broken these terms on their casino:

5.2 In order to register and open an Account you will be asked to provide us with accurate, current and complete personal information, which may include your name, date of birth, contact details (including an address, telephone number and email address), and any other identification that we may ask for, such as copy utility bills and/or photo identification (together the Registration Data). You agree to maintain and promptly update the Registration Data to keep it accurate, current and complete. You should immediately notify us of any change to your Registration Data via the email address you use to register your Account. If you provide any information that is inaccurate, not current or incomplete, or if we have reasonable grounds to suspect that such information is inaccurate, not current or incomplete, we may in our sole discretion deny you access to areas of the Service requiring registration, or suspend or terminate your Account, pending further investigation.

5.4 Letsbet will not register an account on behalf on any individual and, where an individual has already been registered, Letsbet will cancel that individual's registration as a player if it becomes aware that individual has provided false information when registering as a player, and further reserve the right to confiscate any winnings available on the account.

6.1.3 Suspend and/or cancel the participation of an Account Holder in promotional activities, competitions or other services, whenever Letsbet is of the opinion that there are legitimate concerns that a Letsbet Account is, has been or may be used for illegal, fraudulent or dishonest practices.

I have absolutely not broken any of above mentioned rules. I have registered only 1 account which I have provided truthful and accurate information of.

Thank you in beforehand for your help in this situation. I feel like this is absolutely outrageous and that the casino is trying to steal my honest winnings.

Best Regards,

Kimmo
