"Shop owners do not like to use customer supplied parts primarily because they charge a significant markup on the part and make way more profit."
While some of this statement is true it is the primary reason. They want to use their parts for the profit and to avoid situations just like yours. Just like in your case, they mark up the labor to off set the loss of parts profit. It sucks that your problem is not solved after all that money paid but I would bet the presentation to the owner will get some results in your favor. Hell, I know you are mad and want your rig fixed but you are slinging rocks and arrows at this point.
If you had a business that your hard earned money was in, would you charge just enough to skim by or enough to make a nice profit and afford to pay your employees well? I have to say, part of your frustration is because you did not get pricing up front. I asked about that and asked about diagnostic charges and you did not respond.
