The player from Serbia had struggled to complete phone number verification for withdrawal. Despite numerous attempts to contact customer service via live chat and email, he had received no response. After he submitted his complaint to us, we had facilitated communication between him and the casino. The casino eventually confirmed that the phone number had been successfully linked to the player's account and the verification process had been completed. However, the player had no funds available for withdrawal. Consequently, we had to reject his complaint as there was nothing more we could have done.
