Guys
I'm not at all confident that you'll get your money back even if you try.  Several weeks ago, I went to the BA site and was looking around. I checked my invoice, and it had been altered.  I checked my original copy and verified I had purchased for a MARCH delivery.  The invoice had been edited to say it was now a MAY delivery.  I decided to request a refund on Jan 13th.  At first they didn't respond, then they kept asking clarification of what currency it had been paid in (bitcoin) stating that it had to be returned in the same denomination. On 27th they sent me an email saying the funds 'had left the bank'.  Strange place to keep bitcoin, so I asked for clarification and they apologized and said they meant to say they would pay in bitcoin.  They asked for a bitcoin address which I had given them numerous times.

Still no refund

On their internal forum people have been asking the same question about why their invoices had been altered.  The moderators have all been stating that it was a mistake, and just reflects what they are currently selling.  Then the email last nite.  BA has known they were gonna do this for a long time and have lied about it for weeks. Their inability to complete my refund goes way beyond ineptitude, and makes me wonder if anyone will get their money back
