Looks like there was more to this than what was initially thought.
I failed to notice that the email that the player forwarded to me was from
June - I was under the assumption that is was from November.
I finally got to the bottom of this. This is what happened:
The player (who I thought was an Italian player in Italy - he's in the States.) had played some bonus and won $11,000 last June. The email was sent right away congratulating him on his win (before the payout was audited), and this is what he sent to me - which I posted here.
The casino ended up denying his winnings because he played excluded games. But to appease the player's dissapointment, they gave him $2500. He withdrew $2000, and played out the other $500. Over the next few days, he made two separate deposits of $400 - so he couldn't have been too upset over this matter.
But he waits until now to email me, acting as if they were not paying his $11,000?

Is this a case of sour grapes or what? He's in the States and can't play at this casino anyway since it no longer accepts US players.
The operator, (like myself) saw the email for what it was. We both didn't like the language of it; I posted it, and he contacted his office to immediately pay this guy. When we realized that this email is six month's old - and that the player's issue was resloved, shines another light upon this.
I hate it when players pull these stunts.
