I live on an unadopted road. A Virgin engineer and contractors have visited and sprayed outside my house where they are going to dig up to connect my house to the main road. How do I contact the contractors? I have tried numerous times via sales, pre install and messaging on the app. I just get passed around or am waiting for 30 minutes plus. The contractors have sprayed to indicate they will be digging up on my neighbours land which obviously they are not happy about!
