The screenshot shows the btc address where to put the coins.. Why do you say that a different address was generated?

The screenshots of your conservations do not help here... So can you tell why you call the player a scammer? How did he try to scam you?

edit:

I tried something on your site and saw that it is pretty easy to change the displayed address

Maybe you should change it that your site signs the bet address.. then it can be confirmed a lot better
