This is an investment band called Stone X. It seems to be a scam.

After asking me to apply for public offering shares, I was told that I had won the subscription, tied up my money, and told me to withdraw the entire amount, so the fee was 18 million won. 25% loan payment of 20 million won. The cost for the quick remittance service is 15 million won. After payment, they say I now have to pay 36 million won in capital gains tax. They say the money will be frozen if I don't deposit it by today. The accounts are all false. Have I been scammed? I put too much money in it.
