I believe an Apple Genius has damaged my computer, what can I do?

Question

I took my Mac Pro to the Apple Store today to get a heatsink looked at (it's overheating). I know the heat sink retainer clip is broken, you can see it with a flashlight. So I asked the Genius to take a look at it.
He took the processor board out of the machine with a ground strap on and took it into the back room where he continued to take off the CPU heatsinks so he could get a look at the faulty heat sink (northbridge). He puts it back together, brings it back out to me WITHOUT a ground strap on. He tells me they can't sell me only the retainer clip, the best they can do is sell me a brand new processor board. $330. I told him I'd shop around for a better price (come on, it's just a standard plastic heat sink push pin).
So I take my machine home and plug it in and turn it on. No chime, no boot. Uh oh! Maybe he just didn't push the processor board in all the way, so I ground up with my ESD strap and reseat the processor board.
So the machine finally turns on and I get to the gray boot screen, which suddenly has a kernel panic... Recovery partition also gives me a kernel panic... and my snow leopard DVD also gives me a kernel panic... but I can successfully boot to Windows 7! All right!
However, Windows is reporting that I only have 4 CPU cores (the machine is supposed to have 8) and that I only have 3 GB of RAM (I have 6 GB installed)... I begin to think that the Apple Genius has installed the processor wrong.
So I take the machine back to the Genius Bar, explaining what happened to a different person this time (original guy was gone). Now the machine won't even boot into Windows, or even get the gray boot screen... the same issue I had as soon as I got home... Except this time, reseating the CPU board isn't helping.
The new genius starts telling me that the processor board was broken when I came in earlier, and I tell her that this is a new problem that I didn't have before I came by the first time.... The only thing that was broken about it was the heatsink push pin. I explain to her that the Genius before could have reinstalled a processor incorrectly, as I understand that human error happens (I work at an electronics manufacturing company).
She tells me that the only thing he did was detailed in his notes he left behind earlier (which were vague, and left out the part where he took apart my processor board). She starts telling me that there's nothing they can do now except charge me for a new processor board.
I do not want to pay for a processor board that the Apple Genius may have broken earlier today. He was not grounded when he was handling my board and may have damaged something unintentionally. I'm frustrated at the thought of paying a lot of money for something I did not break.
Is there anything I can do? Who can I talk to about this? Apple seems to be impossible to get a hold of.

sorry, but Apple doesn't really read or have much to do with stuff that's posted here. Your best bet may be to speak to the Manager of the store or call/email Apple. Retain all documents,  make your case thoroughly but politely, and cross your fingers. an EECB* may work as well, but be polite-maybe asking to speak to a supervisor?
