And then @OP didn't even bother to reply to the representative and give him the requested username. Now I am doubting the validity of the accusation since, the representative stated that there is no email inquiry about the issue and for the second and third time, the representative asked for the username so that he can verify if there is really that case in their system. @OP better answer the Duckdice representative than answering other users' queries here. Your priority should be establishing communication with the casino representative, not other users,
from what I see OP does not have any valid evidence to support his claim or accusation against this casino, I realized that OP was online when the casino representative made a post asking OP to send the username, OP was online for a long time but not replied to the casino representative in this thread, I still don't know if the OP has PMed the casino representative, but I must say that the OP's behavior is not good at least so far he doesn't seem like the type of person to be making a valid claim with evidence, anyway I could be wrong, anyway in the next few hours or days we will see OP's position
