I requested a withdrawal of my full balance ($2000) after I went on a nice streak in blackjack. (I only play blackjack). A few days later i recieved an email stating that I was randomly chosen for a complete verification process and that my request would be declined. It said I should attempt to request it again a week later. So that's what I did. One week later I made the same request for $2000. I also spoke with their chat support and asked if everything was ok? Were there any issues with my $2000. They told me that there were no issues. I said fine, I want to keep playing so I'll make another deposit and play with that money so it doesnt affect my pending withdrawal. The next day, my account was frozen. I call up and they dont have a reason for me. Tell me to email securi[email protected]blackdiamondcasino.net. It takes a lot of emails and over a week, but they finally tell me that they are voiding my winnings bc I employed the use of a betting pattern. Now, I had no idea what that meant. I was informed that it is against casino rules to use a betting pattern to increase the players edge over the casino. Now, I've looked through a bunch of complaints very similar to mine on askgamblers.com. We all have the same argument. No reputable casino, land or online, will tell you that this is true....There is no such thing as a betting pattern that improves the players edge. It's all luck. There is basic strategy, which I use all the time. Please keep in mind that I have only just started playing online blackjack, so this is a whole new world to me. I chose to try out a strategy (that has in no way shape or form worked all the time). In reality, it usually fails bc the house has the edge. Which is normal. I simply trippled my last bet every time I lost except for the first loss. That I doubled. So I bet 5. Lose. Bet 10. Lose. Bet 30. Lose. Bet 90. Win. Go back to 5. That was my pattern. This is in no way an illegal form of play. If I start with 200 dollars and lose my first 5 hands, Im out. So someone please explain to me how black diamond casino can accuse me of cheating. I've sent them over 10 emails, but they have stopped responding to me.
