I believe that your complaint resolver said that clearly at the end of your complaint thread:
"Dear kosos, I understand your frustration but the casino has provided us with a betting history to support their claims. If you cannot provide us with any supporting evidence that would prove your claim, we have no other choice but to reject this complaint as the disputed funds have been returned and you successfully withdrawn them. Thank you for your understanding. We appreciate your cooperation during the process. If you ever encounter any issues with this or any other casino in the future, please feel free to reach out to our Complaint Resolution Center. We're here to help. "
So, please feel free to provide any evidence you have if you don't agree with the final decision, of course.
I am really sorry that you feel this way about us, as we always try to help players be fairly treated by online casinos, and we always aim for fair play.
In your case, after the investigation of all the provided information by our whole team of specialists, the decision was made, and that is why your complaint was rejected. Please feel free, as I said, to reopen your case by providing any further evidence that will show that the casino was not right.
