Bank placed a hold on my checks?

[WebGuySteve]

So about a month ago I deposited 20K from poker site cashouts. I think 10K from absolute, 10K from bodog, may have been 15/5. At any rate it still has not hit my account so I went in to ask about it and they said a hold was placed on the checks and that I should call customer service. This is Citizen's Bank btw.

Customer Service then told me that they could not give me any information other than that it is under investigation. They wouldn't even put me on the phone with a manager or anyone who is doing the investigation.

Has anyone had a similar experience? Any advice? Thanks Guys.
