There is no point coming on the forum to announce whatever Yobit did wrong without getting feedback from their support. Yobit can be every other thing that does not give regard to their customers or slow to give reply but they are not scammers as at the last time I checked. So you will still have to wait or get back to them to solve whatever you have with them and I am sure that with time they will attend to your request and settle the issue but don't forget to come and update this for the sake of others.
