Some pitiful rubbish about double glazing offer. Hung up and now blocked them. Seem to get them every two weeks or so calling from a new number.

Once a fortnight. Wants to age range, and and claims they're Redoing Roofs in the area, or Redoing windows in the area. Seems they're targeting older houses and people.
