Delayed withdrawal for over a month, intentionally stalling payments without reason

Hi, I've had a withdrawal request of 8.881 SEK for over a month now, and this casino keeps asking me for a picture of my passport and a selfie, something I've provided them with 5 times already!!!! And they still keep asking about it as if they're "slow" in the head! So all I can do now is file a complaint here and see where it goes. Never have I experienced a casino do such a thing. Its disgusting. 5 times have I sent my documents, and they ask about it again and again as if its the first time they're asking about it. They are clearly trying to stall and dont want to pay.
