Thanks, I'll keep at it. It's not really much effort sending them a message every week or so. 99% it's delaying tactics and they have no intention in refunding, but so far they have showed some interest in helping.

Btw, there are so many such posts about Yobit in the Scam Accusations forum that I don't think they care about reputation at all. I knew about this but thought I could quickly get in, buy what I wanted and get out, and it'd be OK. (And for the other deposits that worked, I did exactly that and it was OK) Lesson learned.
