Hi Viv12, thanks for posting and welcome to our community.
I am sorry to hear that your landline is not working for you. And I am sorry for any inconvenience this may cause your household. I have checked our systems from here and can see that you're currently being impacted by a fault in your area. I am sorry, the current estimated fix time is 12:00pm today. I am going to send you a private message. Please look out for the purple envelope in the top right of your screen. Also, for future reference, you may wish to check for possible area faults, here.
