I called this number since my HP printer Ink didn't work, considering the domain name "hp.supportnumber.uk", I assumed it is the HP customer service. I explained the problem, and they offered me a £100 year membership to "fix the problem". I was confused about why would HP charge for support, and asked again if they really are HP's customer support. He told me that they are, and when I asked again of why they charge for the support he hung up.
