BTopenworld has denied that its customer service outfit has been swamped by complaints which have disabled its email service.

Punters trying to contact customer support have had their emails bounced back with the message "mailbox is full".

The email address in question - customerservice@btopenworld.com - relates to complaints about BTopenworld's AnyTime unmetered narrowband service.

The problem first happened on Monday and was supposed to have been fixed yesterday. However, the problem still exists today. It's not known when the email address will be up and running again.

A spokesman for BTopenworld explained that the glitch was a result of a technical problem with the mail server.

He denied that the problem was due to BTopenworld being swamped with complaints about the narrowband ISP's poor service following the migration of some 40,000 to another dial-up number. ®
