CallNet 0800's claims yesterday that it has successfully cleared the backlog of Net users trying to register for its service has been challenged by users who say they have been ignored by the ISP. A number of users have contacted The Register attacking the ISP for mishandling its heavily over-subscribed launch last year. Yesterday, a spokesman for CallNet said that the backlog had now been cleared. Not so, says Guy Turnbull, for one. "I'm one person who called CallNet in the week they launched, and never heard a peep back from them," he said. Patrick Chamberlain said: "Oh really? I've been trying to sign up since a couple of days before they launched, by phone, by email and online. "I've never heard a thing from them. Have they cleared their backlog by wiping their records and starting again?" A spokesman for CallNet said he couldn't comment on individual cases. ®
