Hi @Ann47, thanks for your post although I'm very sorry to hear your landline is down at the moment.
Based on the checks I've just ran, there appears to be a fault on your line.
With this in mind, we'll need to get a technician scheduled to you to get this fault fixed as soon as possible!
Please expect a PM from me to ask you to confirm some details, just so I can schedule the appointment for you and respond when you can!
Many thanks
