Sir, this is the wrong address to complain and no one from here will help you. Not because no one will, but because there is no help in a dispute with them.
Try to contact Yobit but if you haven't much money there I suggest you forget about them and move on.

No one cares about any quarrels in Yobit chat or whenever where did it happen. Everything has been said about Yobit so many times here and I find it hard to believe that someone, despite all the warnings, is still actively using that exchange.
