Well, If he is not satisfied with the answer of Roobet Support. Or If he still believes that Roobet scamming him. He can create scam accusations with all the proofs. All the forum members and DT members with judge them if they really scamming or not. But, Posting these accusations on their ANN affects casino reputations. So, I would like to request everyone to forget it and talk about another topic.
If the support already responded, that’s already final and we can consider the case is close but if the complainant still not happy with it, yes he can always create an accusation thread considering that he has a valid proof. Roobet is still the best, they have a lot of good games and good promotions, they are also strict so better to gamble based on their terms and conditions to avoid any problem.
This is normal reaction for people who doesn't like the outcome of the result of their claims towards what so called issue to them but he can actually appeal if he really think he's right and let the support explain more to enlightened him about the issue. But so far as people speaks about their experiences Roobet is one of the best Casino here provably this issue is just misunderstanding only that's why as what you mention we should read their faqs before gambling to know more better about their rules.
