[BetterLateThan]

I did this:

* Ignored the caller's pressure and sense of urgency.

* Repeated every phrase she told me with a question mark added: "My computer is slow, eh?"

* Every time she said "Yes", I asked my own question: "What department do you say you work for?", "Who is your manager?", "What number should I call if I need more help from you?"

I never let her lead, never said Yes or No and never acted like an ahole. I was nice and calm. In five questions she got very nervous and hung up.
