Now I've got my money. There was an issue with their XEM wallet and with many users arriving. Now I think, that their problem is in scaling and they are not so PRO in making bussiness. They haven't a big state of people, but they add very big amount of coins, which are hard to support. That's why there can be delays - be aware of it - watch at their Coindesk first, and forum - if there is an issues with ur desirable coin.
May be I can give this exchange a second chance. But I will avoid it if there is an alternative at Binance or Bittrex, for example.
