The Washington Post has an article about a new business, "Karens for Hire," that is basically a way to hire a customer service advocate. Having spent way too much time with customer service of late, the article really hit a nerve. It gets at the central problem of consumer law, namely that the dollar amounts at issue in almost every dispute are way too small to litigate. Instead, consumers have to work through customer service and hope that they receive some sort of resolution, but that's a process that imposes substantial transaction costs (wait times, e.g.) and in which the consumer has no guaranty of a positive resolution, even if the consumer is in the right.
There's some level of reputational discipline on companies with bad customers service, but it's pretty weak and indirect: when was the last time you investigated a company's customer service reputation before making a purchase?
There are a few attempts to regulate customer service of which I am aware—TILA/EFTA error resolution procedures and RESPA loss mitigation procedures—but there's no general system of public regulation. Figuring out exactly what, if anything, would work as a more general solution to ensuring fair and efficient resolution of customer service calls remains one of consumer law's great challenges.
