This is the exact procedure for the player to follow when he plays and suddenly encounters some unfair action by the casino administration from his point of view, and it always happens that way. However, the investigation of a difficult situation then drags on for a long time and in some cases generally ends with a long correspondence with the support and a list of all sorts of points of the rules, their interpretation, sometimes the laws on consumer protection in force in the casino's jurisdiction, and so on. However, all this is quite traumatic in psychological terms for the player, who believes that the casino has acted unlawfully towards him and that he has been offended. Everything ultimately comes down to a huge loss of time for the player on these claims and correspondence with the support and very rarely ends with some kind of payment to the player of the money he lost (as he himself believes) and sometimes material compensation for moral damage. All these are extremely rare cases simply because experienced administrators, managers and lawyers of any serious casino understand the intricacies of difficult situations that arise for players when using this casino much better than the player. And naturally it is much easier for them to prove their case to the injured client, including in court.
Indeed things are like that, for us we do not go that far, what causes greater concern is that in some cases there are players who are trolls and invent cases to scam the casinos, that is why most of the time the casinos are the ones who have the reason, now the players have to do things that go further, I always recommend that when there is an accusation of fraud, review the coughs very well, apart from everything always see the threads of this casino in the forum, and of course the screenshots, but what you say is real, wasting time, stress, everything becomes a big problem, well a nightmare, they are very difficult things to face.
You are one-sided here, it's good we weigh the two sides to have the needed balance in judgment for fairness's sake. As we might see ugly customers alleging casinos wrongly, that is the same way we see the ugly casinos that are bent to cheat or even scam their customers, we've seen enough cases to back both sides up.
This calls for the treatment of each case separately and when we are reading reviews and accusations, we should not just read them as if we read the newspaper but read them insightfully so that we can pick one or two errors that would backfire on the accusers, otherwise, they might be telling the truth. I've naturally caught some reviews painting companies back but indeed they are the guilty ones, this also calls for a neutral reading of reviews as biased reading will certainly be unhelpful.
It helps further if either side or both of them could show proof to back up their claims, but sadly at times, since casinos have the system and have locked the accounts of the customers, they have little to back their claims up and I don't see how that is their fault.
