OP you just have to lay your complaints in a professional way. They are sections for this type of dispute. You can as well drop a comment on their official thread. If you strongly believe that they are not trust worthy more people will learn about this on their thread. Most people who use Duelbits may not get to know about this as you claim if you spam especially in the wrong forum. It's important to hit the complaints in front of them and get a responsive reply that will satisfy you too.
