Why do you think 1xbit does not resolve the complaints of its users? They do it all the time. From what I can see, the waiting period for a response may not be very pleasant, but it depends rather individually on the complexity of the case and the overall number of cases in the queue.
Why do they take so long to solve a problem? They are doing business here so they have to work in a professional way, they should have given utmost importance to their customers. They claim they have solved a few problems so far but there is no way to verify whether they are real or not. This is actually a 1xbit strategy to give their customers a little hope that they are working to solve the problems. Any player who observes the activities of 1xbit will think of them as scammers. Because there are so many complaints against a website, and they are not paying any attention to those complaints. As a result, it is clear from here what their purpose is.
In my opinion, the situation is improving. For a long time, 1xbit's problem was that complaints were not considered at all. When the support team changed, complaints began to be considered, but there were still a lot of them. From what I observe now, there are few complaints, and what the accusation are about is for a long period of waiting for a response. A little more, and that will also be improved. It is not easy to rebuild your opinion in such a difficult situation, but as you can see, 1xbit is moving forward all the time.
