Just a small update. I got a reply from them just now :-) Thanks.
OK, just tell us the progress, is your fund unfrozen now? I wish you good luck, nitrogen is the best sportsbook, they will not steal your fund.
Yes, unfrozen and able to cashout. There was a need for the investigation. Reason for posting here is I wanted to speed things up, and was not informed how long it would take. Nevertheless, I'm happy with the outcome as I need the coins to use on other sites. I'll continue to use Nitrogen.
