No response from Yobit whatsoever, I guess it's safe to say they stole my coins

, worst part is that it was a whole bunch.
I feel your pain. Been there, done that. Lesson learned is that you never send any more coins to lower tier exchanges than you can afford to lose. Always do a very small amount send test first to try and protect yourself from that happening and even then that is no guarantee.
It looks like my coins finally showed up, but wallet is still under maintenance and can't withdraw
