This is not right. Your site have errors that cause this problem. I show pics. My balance is .25 in block chainwallet. I would like refund sent to my account it isnt that much problem.
What error did you get exactly? Because looking at your trading history at
https://docs.google.com/spreadsheets/d/1wHIfU_F9ezcLzSN3vI182NuqcgMPKN10Y6lDOjEXiqE/edit?usp=sharingYou took many many bets and had many many winning streaks but you had bad luck when you started increasing your bets and you quickly ended up draining your account. Seems like you legitately lost.
The admin can't refund you because you took a bet and lost. If that was the case then no Casino in the world would work because Gamblers would just complain and get a refund. It doesn't work that way.
