A-Coil from old furnace added to a new Miller Elec Furnace..

I think we have been led down a mis-leading path by an installation company. I hope my post makes a bit of sense to everyone.
We signed a contract "and" have already paid the company to install a new furnace. Part of the service was to keep the A-Coil from our Nordyne Gas furnace and use it with the new Miller Electric furnace (Model E3EB-015H)
The guy that took the order said that his installers would build a metal box around the A-Coil and sit the new furnace on top of that box.
The installers came, removed the old furnace and saved the A-Coil.
They told us it was better to sit the A-Coil on top of the new furnace and lay some filters over it.
They got the furnace working but because they had to sit it on top, the outside line from the Central Air unit was too short. They have to come back on Monday to connect the lines and recharge the outside unit.
Our old setup was exactly how this diagram is so in our mind, the new setup would need to be the same:

The way it is sitting now I honestly can't figure out how on earth they expect it to work. There is no way possible for any air to travel thru that coil since it isn't sitting over the duct work.
Here is a pic I just took of how they installed it. (not the best pic but it will give you an idea) Other than connecting the outside line, this is how they plan on leaving the A-Coil.

Something else that concerns me. I know the furnace was new, I watched them take the band off the box etc, however about 6 inches up on each side of the door there is damage (buckled/bent). It is as if it was dropped. They said they would bring back a new door, but I'm very worried that if it was dropped there could be problems down the road with this furnace.
When the buying decision first started out we were supposed to get a Coleman Electric Furnace, then the company said it would be best to go with this Miller. (Because they had to build the box and the Miller was shorter, but remember, they aren't planning on building a box now)
