and so now they refund you with btc at the current exchange rate ?
That is one way for them to limit the bleeding.
in this case, I'll try to refund

I just send an email for information about refund in btc at the current exchange rate
It will depend on your order size. A single Neptune will be by a bank wire. I saw a response, from Kurt I think, on KnC's forum that said only large orders are refunded by BTC. When I asked about refunding my single Neptune, I was told it would be in USD.
