Have you been able to take a look at our Landline Faults page to see if this can help resolve your issue?
After running some further checks on our system, I can see that there are currently no area issues impacting your landline services. Please run a check on the Faults page and if your issue is still present, I'll be happy to investigate further.
Thank you.
