If you can provide some screenshots of what happened, I will guide you through the process of opening a red flag on their thread. This will help to warn everybody that this is a scam exchange.
I believe that the very first image they created by giving some $200 worth of their CNB shitcoins to everyone joining their exchange. Nobody got the coins when they were faking the volume in there and when it started dumping hard, they began to release the coins to everyone so to make it worth a few cents.
