A priori, I cannot give an opinion with certainty, since we have seen in this section many complaints of fraud that later turns out to be proven to the contrary: it was the player who somehow cheated or broke the T&C, which is what they accuse you
In any case, I don't know if this is normal casino practice in these cases, but when you are accused of something they need to clearly explain what you are accused of so that you can defend yourself, and not say that you have broken the T&C without specify and without allowing you to defend yourself.
Let's say the player is guilty here. But, Casinos are supposed to answer them and refer to the T&C they broke. The Live support is for what? If they answer like they do not have further information, where is the player supposed to contact? I saw some casinos refer them to fraud team email and they take ages to reply. Isn't it better to practice that their support team will contact the fraud team and answer the player? The support has direct contact with the team while a player doesn't have any contact with anyone except for the live support.
I don't remember if have seen this casino before. I don't know why people choose unnamed casinos. Maybe because they want to take some advantage of those casinos? I don't know. If their casino team is here (I am not sure if I have seen them around), they should explain to the player why they blocked the player and what T&C they broke.
