Op, haven't you heard of the saying that don't store your funds in centralized systems? NOT YOU KEY NOT YOUR COIN? The idea of storing funds in exchange is highly discouraged as somany incident similar or even worst than your case is very much possible. As for the exchange you mentioned, it my first time and it still doesn't ring a bell to me. You should try as much as possible to use well known exchange for your transaction. Even some know exchange as still open to so don't store your funds in them.
I don't think there's anything that can be done for now about your funds and you should avoid contacting whoever you meet on social media claiming to be able to recover your funds as many of them might be criminals and you may end up losing even more that already lost.
