Jacksonville Field Office Phone Number Extensions?

[Palmer 12]

Does anyone know the phone number extension numbers when you call the Jax office?

I have the main number of 1-904-245-7899 but the voice prompt give you no info on talking to someone there but does give you the option of "If you know the extension dial it now."

We never received the 797C receipt notice after the 2nd interview that grants her another year on her I-551 after expiration while we are waiting on her new card.

We are traveling to Colombia in December and either need the new card, which I doubt will get here in time since the Aug interview, or the receipt notice 797C that states the card is valid a year after expiration.

Again...anyone know the extension #s to talk to someone there?

Thanks
