i lost 0.15 due to rolling problems and lag, now the site is down

Not sure how lagg can cause you to lose but indeed the site is down.
i was rolling 0.02 bet but nothing happened and my balance didnt change , so i pressed the roll button again many times hope to response but after i closed my browser and reopened i see that i lost nearly 0.14

you said it yourself that you hit the roll button over and over so they were legit bets :O
yes but my balance didnt show that when i was rolling until i reopened the browser
i know the situation but support and more importantly will tell you a bet is a bet
If you would have won their would be no thread post saying please take some away

it sucks but i do have to agree with steve it could have gone either way, could have just as easily won that much. Best to take extra precautions when wagering that much at once and not assume its not accepting your bets, a refresh would have told you something was up.
