Hi Bob_Jankers,
Thanks so much for the update so far. We can certainly sympathise with the issues you're experiencing, especially after 3 technicians visits the issue is persisting.
Due to this I have emailed our area field managers to see what the next steps would be and if we can get another visit done. We have located your account with the details you have provided from your community profile so I have sent this off for you now.
I have placed a copy of the email sent on your account notes as well. As soon as we have a response from them, (This may take a short while as they are not office based) we will post back and update you.
Kind regards Jodi.
