Hi Simone_nettle,
Firstly I'd like to welcome you to the forums and say that I'm sorry to hear that your landline is not working at the moment.
I've run some testing on the line and can see no reason for this, if you've been able to eliminate the phone from being at fault, then the next step would be to arrange for a technician to call out and take a look at things.
I'll send you a private message to get things moving with this. Please look to the top right of this page where you'll see a purple envelope icon, click on this and you'll see my message.
Many thanks and apologies once again.
Huw
