For me I have totally lost interest in them, there’s no way I’m going back to the site [I don’t have any balance there] - if I’m allowed to delete my account I’d gladly do so without being able to log in ever again.
Theoretically, it could be done through a support request. However, as you've probably already noticed, getting feedback from them is no easy task. Even if their site had an option to delete your account, what would be the point? I mean that if you have lost interest in the site, forget and don't use it, especially if you don't have any funds there.
There’s no need for the deletion anymore - I just went to my account and disabled all my email subscription since I don’t want to use it there’s no need for me receiving mail from them concerning bonuses or new offers in their sites.
So, until the sites stops working, that is, until the site goes offline and no longer accessible to any, let's believe and he hopefully that some day, the management of this casino may decide to stand up and fix the issues, until then, lets continue to be hopeful.
The more they wait and let more complaints pile up, the harder it will become for them to clear their name and regain their reputation back - if they had continued giving assurance to the public that would fix their issue or that they are currently working on fixing it (with actual improvements in their site) no one would have even bothered with them but their silent response is only adding salt to their wounds.
