Customer service is difficult, expensive and unpredictable. But it’s a mistake to assume that any particular example is automatically either good or bad. A company might spend almost nothing on customer service but still succeed in reaching its goals.
Customer service succeeds when it accomplishes what the organization sets out to accomplish. Google doesn’t have a phone number, doesn’t want to engage with most users. McDonald’s doesn’t give you a linen napkin. Fedex used to answer the phone on one ring, now it takes 81 seconds for them to answer a call. None of these things are necessarily bad, they’re merely examples of alignment (or non-alignment).
