I successfully got a refund from livecoin. process was complex and took time from January till May.
they could not provide a calculation of how the number came about - but i received 600 USDT, which is roughly half the worth of my coins from February ( SIB + BTC )
Did you provide a receiving ETH address somewhere? I am in the end of this process (received the 'post messages to get the other half' e-mail, but still didnt provide any address to deposit funds). Thx.
