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 were you able to get the bitcoin refund option ? did you phone them, or just send and email request ?
Email request after asking some questions about projected Neptune development with some specific dates to which questions I got no answers except what we already knew about Plan B as a backup to plan A
They said something about that due to the fact I used Bitpay to place the orders, I will receive the refund in BTC:
"HI me,
Yes, we did. However since you paid via Bitpay, we will refund BTC to your wallet, can you tell us your wallet address. Thanks!
