The point is to discourage the customer from complaining because of the harsh treatment the customer will receive. Therefore yes, if it comes to that, it has failed.
Some people complain just so they can watch the boss chew out some employee. That's satisfaction for being badly treated/buying something that was faulty.
It's also satisfaction because you failed to get laid, you are going through a divorce, your own job is a shit experience or your life otherwise sucks in some fashion and you are the kind of asshole who enjoys taking your crap out on other people.
