URGENT..RFE Response under review for more than 120 days

My H1B application was filled by a contracting compay in Sept 2011 and RFE response replied in April 2012. Still as of now for more than 120 days the status is showing as RFE Response under review. Company raised Service Request but there is no reponse from USCIS for more than 120 days of RFE response filling. My current L1 petition expiring in 1 month. WHAT SHOULD I DO NOW ? PLEASE SUGGEST. SHOULD I UPGRADE TO PREMIUM PROCESSING AS THE CONSULTING COMPANY FILLED WITH INHOUSE PROJECT ???
