I have some tokens that only listed on YoBit (I only use Binance and Bittrex as the main exchanges). I created an account at YoBit, deposited and then sold the token for some Bitcoin... then I withdraw my money to other wallet.
Check that transaction in different block explorer and make sure the withdrawal address is correct and yours.
If you can't find that transaction in any of the btc block explorer than its problem from yobit side so you need to contact them and wait for months because they are known for pretty shit customer support.
Try to avoid using them with big amounts.
