My landline is not working. The phone displays shows the message 'check phone line'. I checked the service status and there were no faults. Also an engineer came today to install the landline and he said it was fine on his tester phone.
What I would like to do next is to arrange for a technician to visit your property and investigate this further so I'm just going to pop you a private message with appointment times which you will find if you click on the purple envelope at the top right of the screen.
