I had my refund this week. They sent me a mail, I have had to sign the bitcoin address y paid from saying that after the refund I have nothing to claim from BA nor them from me.
In the mail also they say that they have had problems changing dollars to bitcoin and they only refund the bitcoins I paid minus $50 fee. So I received 9,0.... bitcoin.
In the mail says that If you don't accept this conditions, the order will go on.
I accepted it, I lost more than $2000 in this, but it's better than wait for a unprofitable machine.
That is simply stealing, as far as I'm concerned. nobody's fault but theirs if they didn't convert the bitcoin and lost money as a result, and yet no surprise either.
Being a BA customer is like renting the downstairs apartment in an outhouse.
