Broadband

So virgin can issued broadband to the house opersite my front door .. but don’t issue it to my house I think it’s because my adress is on a private road .. I spoke to two engineers outside my property as the box for the coms is outside my house and they both said it would be easy to do it as just run a line up the wall and into the house - I’ve been on the phone to virgin and explained I’ll pay for a engineers time to come to my house and see what is available and what they can do and she said she asked the question but because my adress isn’t on the the checker they can’t do that - inside the box on the door there was a list of properties and my adress was on there and all the addresses of the private road. What option have I got to get them to to do me broadband I’m currently with sky and because my house is big the WiFi is awful I get 70mpb but most of time I’m using my own 5g because it doesn’t work.
