Hi Sid7,
Thank you for reaching out to us in our community and welcome back, we are sorry to hear your phoneline hasn't been working for a few days and that you haven't been able to get any updates.
Is there any issues showing on Service Status which may be causing this, have you checked the line with another handset and making sure nothing else is attached to the line?
What is actually happening, is it a totally dead line?
Kind regards
Paul.
