Adjustment of Status - I-485

Hello to all,
I have a question, I don't know if any of you have gone through this but I need some advice. ok, so I recently sent forms I-485, I-130, I-864 amd I-693 to USCIS NBC my PD date is 6/2/17. They sent me my biometric date which was on 6/27/2017. Around 6/23/17 my status online changed to "Request of Initial Evidence". First of all, I should note that I am a DACA recipient so I have my work permit(I-765) and therefore di not apply for one when i send my forms I-485, I-130, I-864 amd I-693 . I renewed my I-765 on November 2016 and since yet have not received my new EAD, I have raised many inquiries and nothing yet. So, NBC is requesting that i send a copy of my I-765 apporval notice and a copy of my new EAD card so that I will be considered in my household income because I am married to a U.S. Citizen and filed joint taxes and sent them to NBC as joint so they are asking that i send my new EAD card and the approval of my I-765. So my question after all of this is what can i do? I don't know who to contact anymore, I contacted my congresswoman and she recently send me a tracking number so tracked the number and it says "status is not available". What can I do? please guys i need help, Thank you.
