Well, they jerked me around on a withdrawal once, perhaps because it was a fairly large amount and they were stalling for time. First off, they never told me for several days that it was being held up because the finance dept. needed more ID docs. (They said an email was sent out, but I never got anything.) After I had to bug them about what they needed, I was told that I would have to send a copy of my Social Security Card. I told them no way, because of the potential for that to be used in identity theft, and that there had to be something else I could give them. When they refused to budge, that's when I contacted eCOGRA, who sided with me and told the casino to ask for another form of ID.
If I were in your shoes, I would probably be filing a dispute with eCOGRA by now.
