Broadband providers Continental Telecom and Plus Save have been closed down by the High Court and Insolvency Service.
The firms have been under investigation over the alleged use of unacceptable sales tactics, reports ISPreview.co.uk.
According to the news provider, the firms – which have a very poor reputation for customer service –failed to co-operate with a recent investigation into their activities.
David Hill, Company Investigations Supervisor at the Insolvency Service, said the two firms set out "solely to mislead the public".
"The court's decision to wind them up shows the seriousness with which this type of dishonest customer service activity is viewed," he stated.
Back in December, communications watchdog Ofcom fined Continental Telecom £50,000 for poor service provision and a failure to co-operate with its investigation into broadband miss-selling.
