Hey @davehiggins21,
Welcome to the community and thanks for taking the time to post your issue on the forums.
I'm really sorry to hear of the issues that you're having at the moment with your landline services, I have looked further into this and can see that there is an outage but I'm not sure why its not on the service status page, the ticket number for this issue is F009674662 and the estimated fix time for this issue is today at 6pm. This means that your visit by the engineer has been cancelled. Regards,
Steven_L
