I called the phone number from HP's online support site because my computer was so slow, I couldn't watch videos. The HP tech had me pay $59.95, then told me to download some updates. My computer froze. It couldn't download the updates, so I told the HP tech I didn't want to pay for their unusable support. The tech assured me I would not be charged. I spoke with their billing department to make sure I wouldn't be charged. I documented the case number and the names of both HP techs. I called Microsoft Answer Desk; the tech there found my computer was missing a "background intelligence transfer" code, so I couldn't get updates. He restored my computer's missing code, and fixed my computer. But for the past 6 months, HP has insisted on charging me, though I disputed the charge through my credit card company, Discover. Discover finally credited me $30, because HP refused to refund the amount they unjustly charged me. I will never buy another HP product.
