Hi. I'm another one who has ended up cutting our Virgin cable. I was trimming the bush near our front door and accidentally sliced through the phone cable under the door. The phone is off, but the internet is still on.
wait for VM to get to the thread - they will sort a tech - there are usually 4 wires in the phone cable - all colour coded if there is enough wire you could join them as a temp repair - some insulating tape to keep them waterproof until the tech gets there to do a permanent job
