Just cbecause somebody asserts that something is essential to the economy doesn't make it so, or a good thing either.
Last year I had a problem with a laptop being repaired under warranty that went astray. I spent so many hours talking to call centres at premium rates (or queueing most of the time) that by the end of 9 weeks I had rattled up almost £50 in charges. The people there could do nothing, knew nothing, and could not connect me to anyone or give me an alternative point of contact.
Eventually a colleague who used to be a director of the company gave me the name and number of the company secretary. I rang, dropped his name, explained the problem to his secretary, and it was resolved the same day.
Of course, if everyone rang the bosses it would clog up, but a properly resourced customer service organisation is what people want to contact. And not at premium rates.
