Zapped

Some character claiming to be from MicroSoft called me yesterday from 004721 951 609 about my computer. He started to give me some double-talk about something it was doing, so I asked which version of MicroSoft are you talking about?
    “Your current version, sir,” he said.
    “But I have several computers running different versions,” I told him, which happens to be true.
    Phone down at his end, no sale.
