You could try taking the seat off and putting the seat post clamp in a vice, then you can use the leverage of the frame to try and move it. I've got the same problem but on a 1970's steel frame!
Other than that it's probably a case of keep lubing it and trying it, it will go eventually.

Had exactly this problem on my Dawes. Poss solutions I found are 1- penetrating fluid applied over several days.
2- heat frame tube [rags soaked in boiling water], and ice pack on seat post.
After this it can get nasty and depends on how desperate you are to move the post.
Try not to use your favouite saddle as a twister however, use either moles, stilsons or an old saddle.
Emergency methods are, invert frame, remove BB, fill seat tube with diesel and leave 'till it begins to seep through. Finally you may have to destroy the seat post [as I did in the end] by cutting off the top and sawing a slot lengthways [heck of a job but it works] to allow it to be crushed up enough to break the bond.
This really is a last resort and I'd advise LOTS of time and penetrating fluid first !
Good Luck !

I have had this problem on a 1970's bike... I got around that by spraying wd40 around the seat post the night before and then using a hammer (after removing the saddle) to GENTLY knock the seat post down a little then you should be able to grab it and move it up or whatever.
Just remember to be gentle with the hammer

The Smokeysmoo method usually works

To which I would add
15: Drill a hole horizontally through the seat post near the top. If you have one put a slip hammer on the seat tube, put a bar through the hole and knock it out or use a lump hammer on alternate sides to knock it out.
I believe some people have also used Coke (mild phosphoric acid) to free one up.
