Aluminium post and frame, so thermal expansion is likely to be pretty similar. You say the post has been pushed down to far so its stuck below the ream? I can only think of pulling it out with something, as suggested, that can be inserted and hocked under the bottom. Reaming it out is possible, but you'd need a good machine shop with a big lathe. It'd be worth calling BETD and having a chat with them, see what they think that can do. Also worth speaking to Argos cycles as they have a wealth of experiance too.

Rides: DH - SC Bullit.2/Totems/Hopes. XC - SC Heckler/Pikes(Push)/XTs. Road - Kaffenback. Ride fast, take chances. Just don't blame me when you fall off.
put a spring toggle one of those above ^ ^ ^ in m6 or m8 size down the seattube till it grips the bottom fo the seatpost. somehow fix the m6 or m8 bolt so it can't move now slowly tighten it the seatpost "should" slide out
then get on the phone to the seller and ask him for compensation
Well I've just picked up the frame from the shop which cost me £40. The apparent 'raw works style finish' is actually just nitromors which is eating the frame. I think the slide hammer idea has been exhausted and it can be concluded that it is well and truely in there.
For seized posts, we find Coca-Cola or Pepsi works a well. Once the post is out, you can see how far it penetrates down the side of the post. I was shocked first time my boss showed me!
What slide hammers have been used? BETD have some hefty ones for removing fork bushings that they made, so maybe a bit more substantial than something a usual bike shop may have? I know most of the guys there and I'm sure they would be able to sort it one way or another.

remind me never to take my bike to you shop :S lol... wired way though
maybe if you are able to create like indents down the tube at points.... then get a screw driver and hit it side on,,,,,, maybe that would free it abit as a twist motion will be different to a pull....... for example: some bathroom products you cant pull straight off very easy and when you do they need alot of force........ then try twisting at the same time and it can take less effort
ok i know thats a bad example but i know what i mean... do you get what im saying ??
I've learnt many tricks in this shop from a belter of a manager who's worked in motorcycles and bikes for over 40 years now. Nothing like experience and PMA (positive mental attitude) for getting stuff unstuck! Bet we could do it...
Haha. None taken. He's an older bloke who know's jack about the newer technologies and ranges but he's seen and fixed pretty much every type of bike ever! I'll be stood looking at something with no idea what the hell it is (we get some proper old heaps.... Imean 'classics' in our place) and he'll just wander over and take it apart in seconds. Tricks of the trade and all that! Learnt a great deal from him. Oh, he's the shop manager, not the mechanic btw
have you tried using a hacksaw blade to cut along the inside of the post to try collapsing it? you could pour boiling water on the outside of the frame (or find a way to heat it up) and then suddenly spray that freeze spray stuff plumbers use on the inside of the seat tube?

Where's those funky 'Read the Thread' smiley's when you need em, eh?
The trouble with all the heating/cooling techniques is that it will affect the structure of the aluminium and could significantly weaken it. My suggestion would be to try the hacksaw blade trick, then once you have got nearly through in a couple of places get the whole lot sitting in penatrative lube for a good few hours and have a go a collapsing/twisting it.
If you get some pics it would really help to see what you have to play with!
Get your money back, don't brother faffing about with damaging the frame as then you have no leg to stand on if you do want the money back.
In theory you can take him to court if he refuses to refund you as it was sold in an unuasable state, and not described as such. Take a trip down to your local Citizens Advice Bearu (sp..) and they'll help you out. I'm sure the threat of a beatdown in court would convince him that giving your moneyback is the right thing to do.
