Kaliburz,
I am guessing what Builder is saying is that BillyDon contracted with someone one to repair his truck in exchange for money. The shop accepted his money in exchange for their labor and knowledge in the repair of his truck.
BillyDon couldn't fix it. The shop said they could fix it. The fix was incomplete because the shop didn't do their job properly...should BillyDon have to pay for the shop to learn how to do what the shop said it could do when it took his money! I think there should be some financial adjustment made. If the shop is reputable, there probably will be.
Doesn't there always have to be a person responsible...doesn't the buck always stop somewhere?
