Adjustment of Status - I-485

Had my interview on Feb 08, 2017. We were separated and the interview was conducted separately, the interview was really simple and just asked general questions. Everything went really nice and smooth, in the end the I.O took some documents and made copy of them and also took some of our pictures. The entire interview of me and my spouse took like 15 minutes each. First they interviewed her and then me. The interview was conducted in Houston, TX. Since then we didn't hear nothing from the, no letter sent if there were any issues or if we got approved or any kind of RFE. We called the customer service after 60 days to check on the status., they made SR and told that your case is taking longer than usual and it'll take 30 days to reply you back, no reply after 30 days and called them back after 30 days and all they told us was that we are doing background checks. Then we called them again and made second SR in the Beginning of August and waiting till the 30 days passes and call them again. I see on this forum that may couples from Houston, TX are going through same waiting and never received any notification.

Is any one going through same experience?
