Landline seems to be dead

My wife is away from home at the moment so she tried to call me on the landline. Apparently, it's dead. So I attempted to make outgoing calls. Also dead. Our outgoing calls don't go via the hub, but via the old fashioned wired connection boxes. (Ours is so old it says Telewest Communications on it.)

Tried different phone sets. Nothing works. Attempted to contact Virgin via the website but can't find a viable email address or number for support at all.

I did get an email message in the last week or two, telling me that our forthcoming shift over to the IP based landline system had been suspended for the foreseeable future, but I don't think I'd ever had a message telling me it was about to happen anyway.

Can anyone help?

Edit: I see I've posted this in the wrong forum. Can a moderator move this over to the Landline forum? Thanks.
