The player from Greece had claimed that his winnings of 500€ were deducted, which the casino had termed as bonus winnings. However, he had argued that the winning came from a deposit, not a bonus. We had requested him to provide proof of deposit, and he had sent an email with transaction details. However, we had informed him that the provided proof might not have been accepted by the casino and advised him to get a payment confirmation from his bank. The player had expressed his frustration and decided not to pursue the matter further. Consequently, we had to reject the complaint as per the player's request.
