What turns me off when it comes to gambling casinos are those who don't provide good customer service whenever problems arise. I have read so many posts here about conflicts and concerns that could have been solved easily, yet, the casinos didn't bother to solve it right away. There are so many posts here in scams and accusations board in which clients suffered either minor and major issue. And then when they try to contact the customer representative, it will either not reply to them or make empty promises. This is such a huge turn off because every player deserves to get a nice treatment and resolution. Also, the casinos are responsible to discuss the problem with their customers because without them, it will not be where it is today. They all owe it to their patronizers, but I don't know why most often than not, they forget it.
And all casinos balance on the optimal balance of comfort for players and their own profits. Of course, this ratio is a little different, but the meaning of their actions does not change.
In addition, it is necessary to keep in mind the psychological state of the lost players and their increased aggression, including when writing complaints and communicating with support. Hence the large flow of negativity in almost all casinos.
