Adjustment of Status - I-485

Hey guys, has anyone with priority date November or December 2016 receive any day to go in for 485 interview??? My priority date is December 2016. I haven't heard anything from uscis as it pertains to my interview... when I check the status for 485, it's showing that "As of February 3, 2017 we are ready to schedule your interview." It has been showing that since February 3rd. I plan on going to the Washington DC office to inquire about the status of my 485 application. It has been 188 days today and no interview date has been set yet.... Has anyone went to any field office to inquire about the status of their 485 application??? If yes, could you please advise me on how to get them to speed up the 485 interview process.
