Now I will be realistic here, regardless of what you have been told, the most likely outcome is that absolutely nothing will happen, it certainly won’t be removed because that will cost money and VM have absolutely no incentive to do it.
So I will predict that you will hear absolutely nothing back from VM other than a possible, ‘it has been escalated and is being looked into by the relevant team’.
So personally what I would do is;
a) make absolutely sure that the cable and equipment is on your property.
b) give VM a reasonable time (14 days?) to rectify, after which, go out and dig up and remove any tee point on your property and cut away every single cable at your property boundary.
c) legally this is all the property of VM so not not dispose of it but keep it safe in the event they ask for it back - for a reasonable time frame, six months should do it.
You absolutely cannot just leave it, because that gives tacit permission for VM to use and access your property at any time they like, something you need to declare if you ever want to sell the house in the future.
