If the shingles were improperly fastened, yes you should. If you were making a wisecrack, the joke store called and they are out of jokes.

Yes, everyone makes mistakes, but if he's stupid enough to deny he was at fault on a serious, serious mistake, if it's clear he was at fault, I would drive there in person so he couldn't hang up or get rid of me so quickly. To make a mistake is one thing, to deny it or not learn from it, is quite another.

Be a man. Make a personal visit to the mechanic. Stick the problem in his face and make him smell it, enough so he can't deny he was the problem.
