I believe the rule of thumb is to never gamble more than you can afford to lose.

OP, kindly update us when you've heard back from antillephone. If I am not wrong, basically the procedure of raising a complaint to a licensor is you have one shot at describing your situation best you can, with proper and as many supporting evidences supplied, and the licensor will then move with their investigation by reaching the casino and get to the bottom of it rather privately.

You'll only heard back when they've reach their final verdict [or perhaps they needed more details from you]. At least that's what I understand this far. I'll appreciate if you can give us your first-hand experience in dealing a dispute through master license holder. For my future reference.

And uhh... for the time being though, unfortunately I'll still have to adhere to CG's ruling as a status of your case on my list, resolved, given you both initially agreed to their ruling.
