Thank you for the detailed info, now I will know what they are talking about when I talke to them on Tuesday. I am mechanically inclined (cars, houses, etc.), just not on bikes yet but I am getting there.
Go in there and talk to the bike shop manager only. Be polite, but be firm. If they can't do what you asked, then they should definitely return the bike back to you in the same workable condition it was in. You are right. They should've consulted with you before screwing up your frame, so you knew the risks involved. In this case, I wonder if it isn't a case of the mechanic trying to cover up his error. That is why it is important to only talk to the manger or preferrably owner of the store.
The more you know, before you go back to the bike shop the better. Familiarize yourself with this page. This is where I got the pic of the headset bore holes. Good luck and keep us informed on what happens.
