Thank you for your post and welcome to our community forums. We're here to help.
I'm so sorry to hear you're facing some issues with your landline services at the moment. I've taken a look over things on our systems and there appears to be a known fault in the area that's likely causing this problem for you. The current estimated fix time is approximately 3:00pm on September 1st.
If the issue persists following this time, please let us know and we can go from there.
I have had a look and can see that yes the landline is still non-contactable. I will investigate this further for you. I will send a private message - watch out for the purple envelope.
