Welcome to the Community and thank you for posting. I'm sorry things have gone so badly wrong with the activation of your telephone service. I can understand your frustration, it shouldn't take 7 engineers to activate the service. I'd like to take a look at what is happening with your order.
I have sent you a private message with instructions on how to contact me. You can access your messages via the envelope icon at the top right of the screen, or click on this link, Private messages
