YoBit has a warning not to deposit contract, so you can say it's my fault.
They should refund, however it takes some time. I had a similar situation when using Changenow when I did not pay attention to the warning, and they returned the funds to me a few hours. I believe that Yobit must return your funds, so you should contact their support. If they do not do it, it will be a signal that in this way they are trying to appropriate your funds.
