So I finally got my money out, only took 5 months.

In the beginning of April, about three months after having won, they contacted me with the happy news that my account had been unlocked. They gave me no explanation whatsoever to why my account was locked in the first place. Anyway, I thought that would be it, and that I would get my money in a matter of days. Only problem was that I had to send in documentation. I did send in documentation back in January, which was then approved, but since the utility bill was now more than three months old, I would have to send in a new one. Silly, but I had no choice, so I reluctantly did that, and it was approved within a week or two.
Then I realised that I could only withdraw about €500 at a time. And I couldn't request several withdrawals at the same time, but had to wait until one was finished before I could request the next. I had to request the withdrawals on Mondays, Wednesdays or Fridays between 10 and 16 GMT, otherwise the money would just bounce back. So I did that. After two withdrawals, my account had been locked again. Took a while and then it was unlocked. No explanation this time either. The reps just said that they weren't given any information. I continued to withdraw. If I withdrew more than two times a week, they would charge a 5% fee. I asked if I could possibly get away without paying it, but their answer was that then I would have to wait. They said on several occassions how exceptionally much I had won. Sure €2000 is a nice win, but a casino should be able to cater for that. My account got locked another time, again for no given reason, and then I got my last partial payment quite exactly five months after I won there.
So the actual withdrawal process, when they had verified that everything was fine with my account, took two months.
I'm glad I got my money in the end, but needless to say, I will never set my foot there again.
