The only thing I've found that works when it's really badly stuck, is to drip a small amount--two or three drops--of liquid ammonia into the top of the seat tube and let it soak in. I haven't had to do this for a few years so I can't remember how long it took or how many repeats, but it got a post out that had been stuck in a mountain bike for several years that had resisted all other means.
