Okay. Well, you can forget about your money. They will never answer on your emails agains and the website won't come back.
That's a bitter truth but unless and until the maintenance message is displayed on the site, people still have hope that they may return someday. Especially the people who have money deposited at Betnomi, they want the site to be operational at any cost.

Create a scam accusation against them if want to.
And then what? You clown.
It is doubtful whether the users will ever hear anything again. A whole month without official feedback smells completely like an exit scam. Probably that's why there are so few complaints because every user of the platform is aware that the money is gone.
Yes, if they have already scam, then nothing can be done but still, it is necessary to create a scam accusation so that other people know about it and are being saved.
The site still states that they are in maintenance mode but does not tell any date as to when they will be back.
What is there to save people from? Signing up at Betnomi and depositing? Well that will never be possible because the website won't come back.
