There should be no excuses, if it says that the withdrawal is instant, then it should be instant. I understand a delay of a few hours, even 24 hours, but anything beyond that is just stalling on the part of the casino that hurts them and is very irritating for the users.

I've been waiting for a withdrawal from Frebitcoin for 5 days now... I wrote to support, and I got a reply that they received my request and that's it. That was 2-3 days ago... Except for writing to support we can open a scam accusation here on the forum, and we can do the same in some casino review sites (AskGamblers, TrustPilot...).
