So it would be nice if someone would clarify if this issue of 0.5 BTC was resolved with the email sent by the exchange and if the email was received by OP.
No one knows, this topic has been continued with Email and PMs between op and simplefx, if you really eager to know you need to PM op about it.
He's still online fairly recently, he should be able to answer your pm.
I take it that you have an issue with SimpleFX or just curious?
