The player from Australia was facing difficulties in withdrawing her winnings as the casino claimed she had two accounts. The player disputed this, noting her details hadn't changed and other casinos usually warned if there was a duplicate account. We had attempted to contact Avengers80 Casino, but were unable to establish communication as the casino operated on an 'invitation-only' basis and its underlying platform remained unidentified. Due to the lack of information regarding the owner or service provider of Avengers80 Casino, we had to reject the complaint. We advised the player to check reviews before registering with any online casino in the future.
