I've written it at least 10 times. Their goal was to keep the money on the site and encourage me to play. I didn't win all the time, so I bet I lost until the last cent. After all, if I can't get the money out, the best choice is to bet.
What's the point of playing if you can't withdraw what you win. It's going to be even more bitter if you win big knowing the money is stuck there.
Wait another week while gathering evidence and if they don't give the money back, put all the evidence in a scam accusation thread. Without evidence of their foul play you won't achieve much, especially since there are people who had no problems withdrawing. You have to add some weight to your accusations, so to speak.
