Hi there!
I can partially understand your frustration, but as far as I can tell, the complaint against National Bet Casino was dismissed because, to the best of my knowledge, we still lack expertise in the field of sports betting and do not accept such complaints in the first place.
Are you referring to another case? I must admit that I am not entirely sure what you are talking about in your post. In light of the mediator's final explanation, I would say that he was prepared to go above and beyond for you:
"As you might know, our forum Casino.Guru, deals with the complaints regarding online casinos only. I understand it must be difficult for you, but unfortunately, we don’t have enough insight to take on this kind of issue, related to a sports betting. I can contact the casino on your behalf and try to get some more information, but at the same time, I will be forced to reject your complaint."
To me, this is quite a proactive approach Nick has shown.
Is it about some sort of reopening request maybe?
