So sorry to read about your loss...
Those exchanges know something we don't! With this crash that we are now encountering, the BitConnect scenario, the Bitfinex/Tether scam and so on... It wouldn't amaze me that they are all about to close their doors because it's very likely that regulations are on their way.
Cex.io that have their assets in a war zone, which doesn't make any sense

If I was you, I would head up to Reddit and make a post about your losses, that way, we can all upvote your post for visibility and you can make anyone aware of it.
I hope this gets resolved fast enough.
