@MurrayK89 In your case would run the diagnostic service to see if the line has developed a fault, link is below but you may have to run it over a mobile data connection if your broadband is having the issue!

Try running the line test here to see if any faults are found:

You can also run the test via the MySky app on a mobile data connection.
