Boulder Station Offer Code?

Does anyone have the 4th quarter BS offer code? My mailer is always late and sometimes non-existent. When I call the rewards center I have mixed results, depending on who answers.
My offer code for Sept. was H57BSE7. Or is anyone a "codebreaker" who can figure out what the next code would be?
Thanks.

I can now answer my own question -- in case anyone else is in need of the same information. (I got the code after making two calls to the Rewards Desk.) My offer code for the 4th quarter is H5XBSE7. Obviously, different levels of play will have different codes; I'm at the Platinum level.
