Hi Adam177, welcome back! Thank you for returning to the thread to update us.
Sorry to hear you are experiencing issues with your landline again!
If you ever need to check for outages you can do so here: https://virg.in/servicechecker or by calling 0800 561 0061.
Having had a quick look on our systems there does not seem to be one affecting you currently.
On this basis I will send you a PM to confirm a few details and offer further support.
You will find the PM in the top right corner of the page in your Inbox.
We can then return to this public thread with an update as soon as possible.
All the best!
Molly
