Account closed/blocked and not telling how long they will investigate

I made about 3-5 bets on sports, the deposit was $180. After the betting was calculated, the balance was $ 330, then I decided to go play casino, won and lost money.

After a casino game session on the balance was about $ 500. I put the money to withdraw, went through the verification + additional verification (with a sheet and a passport in hand) - everything was passed successfully, put the money to withdraw, and then a couple hours later my account was blocked (attached screenshot evidence).

Then I was told that they have started checking my account (pre-blocking it) and can not say how long it will take, after reading the reviews in online resources, many people after this check, they just did not respond and dragged time (on responses to other forums (other players) Annex the evidence that they do not say how long it will take to check my account.

I ask you to help and return my money. All of my verification has been passed. I didn't think that a net win of $320 would be a big amount for pokerdom and they would block a player by assigning a verification procedure without specifying its duration, that is, in theory they can run their verification for at least 10 years.

Please help me to stop this lawlessness and get my money back.
