any chance you can provide evidence supporting your claims? I am not saying that you are lying but it is for the better to have posting a complaint like this.

winz.io has a forum representative here(winz.io) who was online yesterday, I'll them a PM informing them about this thread, perhaps they can give more information about your issue. just to be clear, just because I sent them a PM doesn't mean that they will suddenly go on this thread and fix the issue.
