I gave them - passports (my and who made the transfer) , notarial letter, pdf bank statments, photo with docs, skype session, screenshot from exchange... and
in the end they decided to just write[/b] - Unfortunately, we cannot accept any forged data as a valid source of funds report.
No evidence, they just decided to cancel my info just like that, without anything)))))))))
Jeez. even someone else's passport? sounds like they milked whatever they can from you op. They're known for having ridiculous KYC to trap user funds.
I'm not sure if you can still appeal BUT if they ask for more, I advise weighing down which is more important to you -- your funds or your personal documents. Given hitbtc's piss poor history over the years, your information is a lot more unsafe there compared to other CEX. Personally, if I ever gave my passport to hitbtc, I would consider it leaked.
