It is difficult to tell you what to do without knowing why you received an RFE and how you responded to it. You can hire an attorney to assist you. You can continue making inquiries. You can contact the DHS/USCIS Ombudsmen. And in some scenarios you can sue USCIS if they refuse to make a timely decision.
Schedule an infopass and ask them directly. Better than posting on AVVO. At least it might bring some practical results.
