The player from Germany had deposited 50€ and won 500€. However, his attempts to withdraw using a MasterCard had been rejected four times due to allegedly incorrect details. The player had insisted his details were correct and had submitted all necessary documents for KYC verification. The casino had suggested the player clear his browser cache/cookies or try a different payment method. Despite these attempts, the withdrawal had still been canceled. The casino then suggested that the player was entering a non-existent card number, which the player disputed. Eventually, the player had tried to use a friend's card, which led to confusion due to an old card number being used. Ultimately, the player confirmed that the withdrawal had been successful and the funds had arrived in his account. We had closed the complaint as resolved.
