Cash Lotto 1st Prize Winner

I have a question, so I am asking you.

I won first prize in the Cash Lotto.

Since it came in as Dangcheonggeum points.

Use it in the cash deal and the remaining amount

I heard I could withdraw it in cash, so 600,000 won

I clicked to withdraw cash, and it's been about a week.

300,000 won comes into the account, and the rest is

It's not coming in.

I have no one to ask why they are doing this!

Please let the management team know if you see this.
