Kind of odd how they promote these competitions so much then when someone wins something they don't even get anything and no one is willing to help them...
Going through your thread history, you are not the type that creates threads and abandons them; you revisit the thread, so if you do the same here, you should take the suggestion of members who have suggested that you provide more details about your claim on how you won a game and were not able to withdraw it. Even the site link name or image to at least convince people enough to give your thread more attention is nowhere to be found.
It's based on the information that you will bring forward after now that we could decide if the game is real or fake, or if it has gotten to a situation where you can raise a scam alarm in order for other users to take note and avoid such mistakes in the future.
