Pete, if you can't just let it go, I would find out the name of the owner of the shop, and write him a polite letter, describing the events in a dispassionate way, and explaining very clearly what it was about his employees' actions that drove you out of the shop. If he cares, he may try to do something about it.
if he cared, he would have returned one of the many phone calls or did what he promised the first time, or the second time.
somehow I doubt writing them a letter is going to help much. In reality, it's likely that the shop owner would just use it as point of frustration.
If he was gonna fix it... he would have already. Or at least apologized for it. or said "I know we screwed up.... here's what I'm gonna do".
instead all he did was go on about excuses.
(but I understand your suggestion.)
