Bump. I still did not get my money back. They were mocking me and telling me they will have a support team in 2021. We're almost there.
There are dozens of threads about Yobit here in Bitcointalk, some of them dating back to 2015. They had started a popular signature campaign a few years back, but that campaign was nuked by the moderators. And it surprises me that people continue to use that exchange, despite numerous complaints about their services. You can check the trust ratings for the Yobit account here:
