Leaving negative feedback on Betnomi profile is probably only thing what we can do, though, it's pointless, I doubt that in future they're going to something with Betnomi brand, it's possible that they will come with new brand.
This is one shitty revenge move from betnomi, but they are only hurting themselves more with distrusting members who gave them negative feedback and support flag against them.
I think they will comeback or maybe they already did comeback with different name, so be careful with all new casinos that appeared in last few months.
I dont know what they expected from everyone, website is not working for many weeks, they left without any explanation, and they owe money to people who worked with them.
