BT has launched a new service that promises frustrated broadband customers that they can speed up their internet connection – or they can get their money back.

The company has vouched that it can improve speeds of people’s broadband by at least 0.5Mbps (megabits per second), regardless of who provides their internet.

As long as the householder has a BT land line they will send around engineer who can help the customer speed up their service, either by de-cluttering their computer or by rewiring some of their sockets.
