Got Cc'd on an E-mail chain from the assistant to some senior VP at DHL once, where the threat that said SVP wanted updates magically caused a package that support had claimed was already on a freight ship across the Atlantic in the wrong direction back to the sender to turn up in a depot five minutes from my office.
I'm currently getting screwed on a >$20k purchase and the ebay dispute resolution response has been idiotic -- basically demanding documentation from UPS that AFAICT isn't something UPS provides, when it wouldn't matter in any case (seller admits that the merchandise is currently in his possession).
It's taking an issue that reasonable people could resolve in ten minutes minutes and going to make it end up in litigation for no good reason.

Maybe tossing people into a bureaucratic maze just makes them go away when it's a low value purchase, but that isn't going to happen in this case.
