Sorry that there is no dial-tone at the moment.
I would suggest firstly that you try some troubleshooting in the landline.
If the above doesn’t fix the problem, then I’d really recommend getting in touch with our team on Messenger so we can log a fault.
Please note, our Messaging team are currently experiencing delays so it's best to complete some basic troubleshooting before getting in touch with them
Ask to speak to a human, then leave your full name and the information about the issue in the messenger window
Hope this helps
