The player from Austria had reported an issue with Vulkan Casino, where he had two accounts. He had requested the casino to lock the unused account, but instead, the casino locked the account where he had deposited money and won 3500. Despite his efforts to resolve the issue through chat and email, the casino had closed the account. The player had sought help from the Complaints Team to collect his winnings. The casino defended its actions by stating that the player had violated their terms and conditions by having two accounts and using a no-deposit bonus on each. The player had denied using a bonus. We requested proof of the player's bonus history from the casino. After reviewing the provided evidence, we concluded that the casino acted within its rights and rejected the complaint.
