Scammers Profile Link: http://yobit.io  

Amount Scammed: 717 ETH / ~ 1 million US Dollars
Payment Method: Withdrawal Request
Proof of Payment: http://tinyimg.io/i/7IAP9YL.png
PM/Chat Logs: No Reply at all, tried Support tickets, Twitter, Chat.
Additional Notes: I understand it is a significative amount and all I want is YoBit to cancel the withdrawal and I'll do several small withdrawal in different dates however they are not interested in reply to support ticked.

Question is: If they don't care about 1 million dollar problem will they care for small amounts?

UPDATE: Got the coins few days after this post.
