Hi BT has currently just been installed for my neighbours downstairs. They have obviously had to dig. They have left such a mess in not sure whether they should be coming back out to do something with my garden. My garden was never like this. It's not allowing me to post photos
It was not BT who are responsible for the installation but probably openreach if neighbour was getting BT Broadband installed so you need to contact openreach

If you neighbour has a problem with the installation then they must submit any complaint. To post a picture just click on the camera icon, if the image is too large just use an online optimiser.
