It is the same concern I also stated in my previous comment, but i sense that maybe op is not good with English and as a result, lack the proper English words to really express himself by explaining the situation in full details, but then, what ever be his or her reason for an incomplete complaint, the fact like you said, remains that there is no way we could help as a community, and for the fact he didn't even mention the casino or platform that organized the said competition or contest is another barrier altogether..
Anyways, let's hope he comes back with more detailed report of the his situation.
Apart from the complaint statement given by the OP which is not very clear, I actually have doubts and also a little distrust of the OP's complaint.
Maybe the OP gave an incomplete statement and also he couldn't include the name of the casino that organized the competition as you said so that makes us all have doubts.
Actually in this forum there are many examples of complaints that OP can emulate, namely providing all the clarifications and also other facts but never mind why should we think too much about things that have not been proven to be certain.
