Option one: hang on for a member of the forum team to respond and offer to pass your request onto an ‘area manager’ who may, or may not respond and get someone out to remove the cables for you. Timescale is a bit vague though.
Option two : cable cutters and a convenient skip! It’s perfectly safe, there is next to no voltage on the cables. Theoretically it could cause issues for your neighbours on VM but I’m willing to bet that the ends of the cables haven’t been properly terminated anyway so irrelevant really. Either way not really your problem.
But, in the interest of fairness, give VM a chance to respond and do things properly.
