You can still show us the transaction from your wallet if you want. I'm not saying it will prove who is right and who is wrong in this case; what it does show, however, is that at least part of your story was true: there really was some money transferred between you and the casino.

I can imagine that you are upset over being banned and that this was a very frustrating situation for you, and I appreciate your willingness to try and shed some light on the details. However, based on the information that you've given to us so far, I don't feel that there's enough evidence to conclude that the casino acted improperly. The evidence that you've provided so far is simply not conclusive.
