Hello, and thank you for reaching out and for being honest about your situation. I understand this is very difficult for you.
Casinos have different policies regarding responsible gambling, including limits on withdrawals or account closure for players showing signs of gambling-related harm. If an account is closed due to gambling addiction, it is often treated as part of their internal responsible gambling policy, which can unfortunately include forfeiting winnings, depending on their terms and conditions.
Whether such a decision is "fair" depends on the casino’s terms and the context of the situation. Generally, if the casino acted according to its published rules and responsible gambling policies, complaints about account closure or confiscation of winnings need to be investigated properly with Casino Guru’s assistance.
That said, my colleagues may advise you on the complaint process, help you check if the casino’s policies were applied correctly, and make sure your complaint is heard. But please be aware that there is no guarantee of winning the complaint. It always depends on the findings and concrete situation. So, go ahead and complain; it's free, so there's no need to worry about the consequences.
Most importantly, if you feel that gambling is becoming harmful, it may be safer to self-exclude from the casino or seek support from responsible gambling services in your country. This is often the most effective way to protect both your health and your remaining funds.
