2 weeks went by, no response via email, none whatsoever.
I don't know if this is true but given the volume of people that's requesting a refund and are angry at Betnomi, I think that you shouldn't base your belief in Betnomi by their response time to their emails because they're getting a lot of hatemails already and it's an instinct for them to ignore it and basically your email is probably drowned in spam and hatemails from other players. Maybe you can hope that you'll be able to get some response from them now that you've exposed yourself.
They already stated on their previous post that only few left that still doesn’t receive their funds before they close. The large volume of fake claims is very easy to address since they have all the original information of their players including email.
The email itself is sufficient to claim the refund without the need of KYC unless they imposed KYC to all their user before then KYC really matters at all. They should have at least process the first batch if they are really serious about this refund process.
