Thanks for posting and I'm sorry to hear that you're without your landline at the moment.
I have checked your line and I'd like to arrange for a technician to fix this for you so I'm just going to pop you a private message which you will find if you click on the purple envelope at the top right of the screen.
An engineer came for a brand new bundle installation last Wednesday. Broadband and TV were successfully installed, but I had no phone available to test the landline. I plugged in a brand new phone on Saturday but there was no dial tone. I ran the online tests and there seems to be no problem with the line.
