Let's be fair @tread93
Are you sure you really wanted them to send you back the BTC minus deducting any withdrawal fee?
I have seen worse exchanges that don't even bother letting you get back some of the money and all they do is keep saying that you breached their terms of service.
As far as I know about the Internal transfer (sending bitcoins to another Binance address in order to get the withdrawal fee refund), I am not sure if it also works between Binance.com and Binance.us accounts, but I am more that certain it works between two Binance.com account addresses.
However, the BTC will not be part of your sent BTC, it will remain in your sending account. Check your Binance.com account to see if there is any 0.0005 BTC remaining. If it isn't there, then sorry.
