Withdrawal is not possible.
There has been no withdrawal for the past 5 months. I sent an inquiry email, but there was no response and they just told me to contact MIB.
Unable to Withdraw
The following is the original recommendation
출금이 되지않습니다.
지난 5개월동안 출금이 되지않고 있다.문의 메일을 보내도 답변도 없고 MIB에게 문의하라고만한다.
