So I think I shouldn't worry that much and just wait.
Do they respect the 24 hours delay they announce ?
Unfortunately, there have some issues with freebitco in the past months and the support is not responsive to the complaints, but as far as I know, bitcoin withdrawals are working fine and I hope you will have your withdrawal processed soon.
Do we have any case here where a user couldn't withdraw BTC ?
I remember cases in which people couldn't withdraw their fund and they were banned due to abusing the website.
