If it's still under warranty, I would let the shop/dealer sort it out.
If the shell is off (which it may be, bearing in mind how new it is) then there's little that can be done to fix it.
You won't get a new frame if you've pulled it apart.
It'll be in warranty so that's not a bad idea. I'll give Paul's cycles a bell and see what they say.
When you say the shell is off, do you mean the frame is broken or the bb is broken?
