Narrative:
While en route from maryland to maine, ZDC handed me off to ZNY. I attempted unsuccessfully to raise ZNY twice then saw an air carrier B737 or B767 coming straight at me. I immediately climbed 500 ft and turned 45 degrees to avoid collision. I was then able to reach ZNY controller #1 and explained my situation and checked on. Controller #2 came on and explained that air carrier was at least 800 ft below me. Controller #1 then cleared me to 13000 ft and then 11000 ft, but before I descended 1000 ft, controller #2 came on and sent me back to 15000 ft, saying they had made a mistake.
