I will advise BetHong to please try to solve this user's allegation. You can say clearly what was wrong and how this user abused your terms. Since the question was raised, it's better to solve it here; preferring to contact through mail won't be much helpful. When he didn't get a reasonable answer from the mail, then he came here. It's a matter of your reputation, of course, and it may affect your platform.
I think they should have their Representative account to get more active here and respond to such issue instead of the campaign manager being the one to mediate between the issue. The CM mosts deals with marketing and not dispute resolution
@BetHog, this should be a scenario where customer representatives come in and help resolve any issues and not let them drag on for long. This can damage the reputation of the casino.
