Adjustment of Status - I-485

Hello All, so today is another sad day for me again, i call in to speak to lv2 officer about my EAD 88 days wait, i was ask to hold for a call back with which i waited. When the lv2 officer call me back an i explain that it's 88 days as of today and this is my second SR, he then said the timeline to take decision is between 90 to 180 days, that i should just wait between that time. This is really sad that i EAD will be estimates for 180 days, the previous lv2 officer told me i will hear from them within 7 days, but today this officer said different thing from the previous one. I see people raise SR an get response within days my case is just a sad one, but i bless God and will keep waiting. My PD 17th March 2017. Pls anyone with similar case should share their timeline
