Few days ago I accidentally went to their exchange and the chat box is full of those people that has been complaining about the same situation. And yes that's the guy that I've read and the support, IIRC the name was 'dominik' something like that and said that always contact yobit through their suport.

I don't know if there's really happening contacting them through their ticket. But if someone contacts you and want you to deposit money, it's an obvious scam attempt. Supports don't require money to solve your problems.
