Well, I'm not sure if you bothered yourself to check that particular exchange before depositing. Because if you did this surely you will end up like that.
I may give you sympathy because of your losses but I hate hearing like this for this is not supposed to happen if we care to check the site and if we never use non-reputable exchanges. In fact, I'd never heard of this exchange and probably was newly created with the purpose to scam people (like you) who miss to asses the site.
