I think it's at least slightly funny* how customer service phone mazes work.  Here's a typical example: 

1. Press 1 for billing.  Press 2 for tech support.  Press 3 for all other inquiries.  You press 2.
2. Enter your shipping number or product code.  You enter your 29-digit number.
3. Enter your zip code.  You enter your zip code.
4. Say your first and last name.  You say your first and last name.

Here's what happens when a person picks up: 

1. "Hi, this is Rajuswami Ricky from India Texas.  How can I help you today?
2. You say, "I'm calling for tech support."
3. They say, "Let me transfer you to tech support."
4. Tech support says, "Can I have your 29-digit product code, your zip code, and your first and last name?"
5. You hang up with murderous thoughts on your mind.

An obvious question arises:  Why did I do all that stuff and press all those buttons when I first called?  The not-so-obvious answer:  These systems exist for the purpose of stalling.  They don't actually provide any type of benefit.  They're like Kramer on Seinfeld:  "Why don't you just tell me the name of the movie you've selected?"  All those buttons you press are like the buttons on a child's toy phone:  They don't do anything; they just have an appearance of doing something. 

And I have it on good authority that the main purpose of customer support is to get you off the phone.  The less time they spend with each person, the more people they can not help. 

*Funny obviously isn't the right word, but I couldn't think of a better one that wasn't preceded by several 4-letter words.
