Guts Casino - Locked account and doing verification 3 weeks

I opened new account, because reviews are positive and payments are fast. I was playing 2-3 months. Deposited a enough money. Not small amounts. One day won $1800. Sent for withdrawal $1600. Right after that they blocked my account. They asked me to do a verification process. I sent everything that was required, after they asked to proof an address again, because they don't accept what I sent (but it was a paper mail, showing name and address, don't understand why it's not good) but ok, I sent 2 different documents to proof my address. So they accept them, told me everything verified and ask me just to wait 24-72 hours and they will reopen my account.
But then this problem just started! They told me they need to see some transactions from bank account showing deposits. So I sent that. After they told me another department has to check that, but it took so long. I chat with them every day and they keep saying same things everytime: please wait the relevant department working on it".
After I got email from them to fill up questionaire "Source of Welth" - my annual income, how I'm getting money etc. It was very strange, because even banks don't ask that kind of questions if you come to open an account. But I really need that money, so I sent them this too.
After that they were just ignoring me, in live chat they were saying wait 24-72 hours, after a week they didnt even say 24-72 hours. And I was very upset.
After 3 weeks of waiting I went to another live chat, but they page of chat was unavailable. So I email them and asked what's going on with my account? They reply same things that relevant department is checking my account. After 3-4 emails they reply me this:
