I'm calling it SOLVED. but i'm skeptical about their sincere operation of an exchange.
Hopefully you get back the token, even this has been solved... it's doesn't mean 100% safe. I suggest to move your funds to more popular and trusted exchanges (e.g. Binance). Keep in mind, don't hold your funds inside exchanges... because its not safe. You need to hold on your wallet.
Anyway, please revise your topic "W A R N I N G" to "RESOLVED" and lock it.
