Second, you also do the wrong thing from your end by using a VPN to access a gambling site which is against the rules and regulations of every gambling site.
In the meantime, I hope they will provide you your fund so they could at least convince us that they have changed.
I have posted this a few places, and everytime one person has pointed out, wrongly, that VPN is banned. The rules are "Nitrogen reserves the right to deny its service to players from countries or regions where sports betting or cryptocurrency activities are deemed illegal. Therefore, the use of obfuscation methods such as IP masking or proxies is not permitted." But neither are illegal here, so the therefore doesn't make sense. Also, suggesting fire insurance after a house fire is not helpful.
