This has been raised many times on the fora and I dont recall VM ever stating what their position on this is.
Are you contemplating joining VM at some point in the future - if so then obviously do nothing until that time and choose a "manned install" and at that time get the Tech to resite the cabling to your satisfaction
If not all I can suggest is that you contact VM on the phone, text, chat or in writing and tell them they have 28 days (?) to remove the cabling and terminate it properly or you will remove the cables yourself and store them in your shed if they would like to retrieve them.
If you call (0345 454 1111) do it at 08.00 Mon-Sat as you get through quicker at that time. I would try the wanting to leave or join options -f they are presented to you
