Euro Palace Casino - Confiscated unfairly legitimately won money

Hi, please AskGamblers, help me get my withdrawal from this fraud casino group.

To start the story, I've played LOTS of different casinos. So I found this Euro Palace Casino that looked really good, I liked the layout and I thought it fit me perfect with all the different games. Casino, Live blackjack, Roulette etc.
So I started in Oktober 2018 so make a couple of deposits, I lost most of them. Then I got a bonus offer, I think it was 100% bonus, so I thought I'd give it a shot. I looked through all the terms & coniditons and I am SURE I didn't break ANY rule.
So the maxbet was 75kr. I usually bet 30kr, but since I got a 100% bonus I thought I could bet 60kr, like I did.
I had a really good rush and I made it up to 56000kr (5600€~). I was aware that I had to wager my money and I did that - still without breaking any rules.

After I had finished my wagering I kept playing for weeks, maybe months. I played blackjack, live roulette, Live blackjack etc. I didn't have the same luck and lost my money to 40000kr. I thought it'd still be a good win and I asked the support if they needed any verification so my withdrawal would go smoother. They asked for my verifications and I sent everything.

I still keept playing after my verification was done and I went up and down with my winnings, until I hit the 40000kr again. Then I got a e-mail that the EuroPalace would be shut down for swedish players at the end of the year. So I made the withdrawal around 20 dec - I heard nothing for a week and I wrote to the support again 28 dec (friday), they said everything looks fine and that my withdrawal would been paid out LATEST monday (31 dec), because of holidays.
I went to the support at monday and they still said everything looks fine and that it would take max 24h until I have the money on my bank account.
Two days later, today (2 Jan). I write to the support and asking what's going on. They are telling me that I wont get my money and I broke the bonus rules almost 3 months ago??. I asked what I did and they said I made 500kr bet (mostly 160kr bet). On the roulette and Blackjack.
I told them that that was AFTER I wagered my bonus and it was "my money" on the account - he said that he was sorry and couldnt help me - I needed to send them an E-mail and that they will look at it.

Please ASKGAMLBERS, help me with this one!

I attach some files from the chat (in Swedish). Let me know if you need me to translate the conversation.
