Yobit.com - Scam Support

What happened: I did an arbitrage trade and was silly enough to use Yobit. I bough BTG at one exchange, sent them to Yobit and wanted to sell them there.
(1. mistake from me to trade there and not look wether the BTG-Wallet is on maintenance..) The wallet was on maintenance and I opened an official support ticket at yobit
to ask when the yobit wallet of BTG is online again.
The chat with the support worker from yobit that contacted me after I opened the support ticket is in a link below.
He said he can manually withdraw my coins with the yobicodes (2. mistake from me to send him those codes without any security. I should have stopped there and I hope this helps to prevent more damage.
He first told me to send him the BTG for the withdrawal and then he told me that I have to send him 0.1 BTC to verify myself at Yobit.. Please read the chat and you'll see that he really talked so much bullshit to get me send more coins.
If you have the same withdrawal issue please don't let yobit withdraw manually!!! They won't send you anything and always will find problems so you have to send more before you'll get your coins back..

Don't use Yobit! It's a bad exchange and there a much better opportunities. If an arbitrage deal looks to good to be true you shouldn't do it. I learned that now on the hard way.

Can someone help me here or did someone make the same experience? I hope I can find a solution for this issue and if not I hope this will help someone to not do the same mistakes I did. ::
