Internet service provider Zetnet has left many of its broadband customers without properly functioning email access for two weeks, it has been reported.
According to ISPreview.co.uk, a number of consumers have complained that they have been unable to access their mail.
Other complaints included the fact that several hosted websites allegedly went offline while ftp access is also reported to have gone down.
The website quoted one broadband customer as saying: "All emails are ignored and customer support seem impossible to get by phone, plus it is now 10p per minute.
"It seems the UK regulators are totally useless as I have found with them before."
Another suggested that they had decided to switch broadband suppliers after claiming to be left without the ability to send emails and also being inundated with spam.
Zetnet specialises in ADSL broadband lines for home users with speeds ranging from 250Kb to 2Mb.
A statement on its official website reads: "We are currently in the process of moving your mail to our new email platform. Be sure to read the following announcement to see how this affects your email."
