The player from Switzerland had his account unexpectedly closed following a significant win. This led to the cancellation of withdrawal requests and approximately 1730 CHF became inaccessible. Despite his attempts at contact, he had received no responses. We had reviewed the case and had reached out to the casino for an explanation. Based on the evidence that the casino provided, it was revealed that the player had been betting on opposite outcomes using two or more accounts, which was against the Anti-Money Laundering (AML) rules. Therefore, the player's complaint was rejected and he had been advised to refrain from such strategies in the future.
