The secret here is that for the majority of companies, the goal is not to support you as a customer effectively, but to rather minimize the amount of time spent organization wide supporting ALL customers. So to that end the automated systems are about frustrating customers to the point that they'll just "Go away" and the voice based systems are more frustrating than the button based ones, and infinitely more frustrating than actually talking to a human being who can actually help you, so it's a win for the majority of companies that just view customer service as a cost centre to be minimized, and it's a win for the SAAS companies that sell these useless, irritating and anti-consumer systems.
