I've been offered the option to refund in BTC at Bitstamp's exchange rate at the moment of the refund taking place. The really weird thing followed shortly after I requested refund on my 3 Neptunes, when they said it will be processed within 3-10 business days. Wasn't aware a BTC transfer might take so long (probably they're typing my wallet address 2-3 characters/business day?) 
How the Hell are they supposed to send you BTC from Bitstamp when BTC withdrawals are frozen for the past 2 days?If they COULD...... would you want them to, knowing it could get lost in the transaction?
Best to wait 'till the withdrawal bugs are fixed.
and..... Could you post a copy of that E-mail where they offered a BTC refund for Neptune? I have a hard time believing that one.
