The player from Australia had deposited $4000, won $11,000 and converted a bonus to cash. However, when she tried to withdraw the winnings, they were cancelled without any explanation. The casino's customer service had provided no assistance with the issue. We had invited the casino representative to join the conversation, who then claimed the issue had been resolved directly with the player. Despite our attempts to confirm this with the player, we received no response. Consequently, we had to reject the complaint due to lack of confirmation from the player.
