I invested during the pre-ICO. And I want a refund because I don't want to send my personal information. If that personal information is still required to get a refund that would not make any sense (then I better keep the tokens...). I have invested ETH, they didn't need to know me when they accepted my money. So why do they need to know me when they send it back to the account where it came from? Money goes from A to B. After a couple of months it goes from B to A. It has nothing to do with any risk of money laundring or financing terrorism... If they send it back I am not their customer, I did not buy anything, so why do they need to know me (KYC) if I am not a customer?
Absolutely correct. In fact, thanks to the blockchain, they know for each account exactly how much was paid (in Bitcoin or ETH or both) and the address(es) the amount was paid from. To refund, they simply have to reverse the transactions, i.e. pay the same amount(s) (in Bitcoin or ETH or both) back to the address(es) they received the money from.
I think they have written in a white paper, that all funds are non-refundable.
