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,
Because of the high rate of fake accusations from newbies without relevant evidence it has made it look as if this type of accusations are sponsored by passive rivals who hide under newbie accounts just to cause fuds for their competitors.
If oos is serious and have any level of evidence and truth in what he said, then he should have created this thread in reputation, accompanied with relevant evidence for clarity.
But in this case, the ops just created the thread and ran away without any response.
