so here is what happend, i was using a betting style with small odds. I deposit 0.05 and betting 1000satoshi to every bet. So i have earn like 0.09 btc. Using automated bets after 300 bets on one dice the bet was internaly stoped and I had to take a new bet but 0.7 from my bankroll was gone. I tried to complain cuz it was obvious an error and it is easy to verify in history but the custumor support is not working so... yeah...
