Me too
i sent usdt to btc wallet in binance exchange
and binance support said
"Your transaction has been confirmed in the block chain already. Which means that Binance has transferred coins in the block chain successfully.

If your still has issue on the transaction. It is suggested to negotiate to the owner of designation address or target wallet kindly. Sorry, Binance has no way to help you at this moment."
I lost all money . Very sad,
