Question Author
Thank you buildersmate. I rather thought it might be the case that I can't get a cheaper line. It seems there is no option other than choose the cheapest plan which I believe I have done, although I'd prefer not to have a plan at all and just pay for whatever calls I make. Being a fairly home-bound person I don't feel I would want to be without a land line, although mobiles are useful. I wonder if any reader has experience of other telephone service providers.
