OP is so wrong. (my post has nothing to do with BFL and/or delays/scam. This is strictly about refund)
Here's what OP wants.
Pays for preorder in BTC at (I believe) $2600.00 back whenever (think in chat he mentioned 193 BTC). When requested for refund BFL gave him 60 BTC since at current value 60btc=$2600. Well he wants his 193 BTC back.
So we ask him what if BTC was lower, then he states he wants his $2600 worth back in BTC.
You can't have it both ways. You paid $2600 and got refunded $2600. It's not BFL's fault btc value has changed so much in such a short period.
As to BFL, I have no opinion. I ordered a jala just for shits and giggles. Not a serious miner or anything. Just have 1 gpu at 50% running for the occasional btc for stuff. I paid for mine in $USD.
(non BTC example, you buy something from US in Europe over ebay or w/e. You pay X$ to be converted into Z euro. You get item 2 weeks later. Want refund. YOu ship back, month has passed. Person refunds the Euro they received, if exchange rate has changed you may get less or more USD. )
FTFY - OP purchased 2 Singles @ $2600, not $3600.
What's interesting is that OP was refunded 60 BTC, which today is valued at almost $4500... hmm...
Yeah my bad. Still. My point stands either way.
