Thank you for your post and welcome back to our community forums. We're here to help.
I am really sorry to hear that you're experiencing some issues with your landline service at the moment. Have you checked our Service Status page yet to see if any known area impacting faults relating to this are currently being reported?
Sorry to hear of the landline issues you're experiencing and thanks for checking for area issues.
I've ran some further diagnostics from our side and can confirm that this does require a tech visit. I've gone ahead and requested the earliest possible appointment slot for you - you can check this via your My VM Account and amend this if needed.
Please feel free to drop back after the appointment and let us know how it goes 🙂
Thanks for popping back to our Community - so sorry that you're having some further landline issues.
On checking your account I can see that you are currently impacted by a known area issue. This was raised earlier today under reference number F008996260. At the time of writing, the estimated fix time is 6pm today.
