Case File Review Notice w'out Interview Date

[mrslef]

Hi, i started the N400 process in late May and completed fingerprints as scheduled by USCIS in June. Approximately a month a later, i received the yellow Case File Review Notice that says:

"After a complete review of your file and Application for Naturalization (Form N-400), this office has found additional documentation may be needed. unless previously submitted, please bring the below requested documents to your naturalization interview. Please do not mail in these requested items."

The letter goes on about providing original copies, etc and ends with:

[x] Bring your state-issued driver's license or state issued photo identification card.

I'm sorry if this has been asked before but how do i find out my interview date? I called USCIS and i cannot get out of their pre-recorded messages to talk to a rep. Online, there is no update for my case.
The Case Review Notice is from NBC, and my fingerprints were done at the Field Office in Honolulu. How do i find out whether i have been granted an interview date?

Thanks
