Voilà£15 for a new landline??? Please tell me where I can get one as cheaply as that. The ones that I have seen are at least double that amount (some even more). I don't shop in Aldi or Lidl. If I paid such a suspiciously low amount for a new handset, I would fully expect it to pack up within six months. You get what you pay for.
Back up and running and your appointment sorted with change from £20.
