Pipex?
I got a broadband connection from Pipex several years ago which I still have.
Everything (letters, emails) come through marked Pipex but apparently they were taken over by Tiscali some time ago? If you go to Pipex's website, you can be classified as an existing Pipex customer from a company called Pipex, but you can't create a new account because the company has been taken over.
What's the deal with this - does anyone know? I'm not joking, I seriously don't know.
When I phoned their customer support (to get my "free" upgrade from 2Gb/month to a whole 10Gb?!) their customer support didn't seem to be able to shed much light on it.
