Adjustment of Status - I-485

I applied in June 2017 and I received my Employment Authorization Card in December 2017 along with notice of interview. My wife and I went for the interview in February 2018 as scheduled in the notice that I received. The lady who interviewed me said she had doubts our marriage was real. She had 2 agents show up at our apt in April 2018. They questioned both of us that morning at 6:45 am when they showed up. They agents also went to my father in-law’s job to question him and also went to his home to question my wife’s step mom. I have been married for 3 years and it will make it 3 years that I sent in my I-485 application in May. The latest status on my I-485 application is my interview that was scheduled for February 2018. What can I do at this point to get them to give me an update on my I-485 application? The field office in Louisville, Kentucky doesn’t allow InfoPass. And, I have sent several e-requests with the Self Service Tool to get updates and they don’t ever respond to me
