Personally I don't think VM should open what is rightly theirs!
Who cares if BT open their ducting???
I know BT are currently in the process of implementing this new network, which in itself is a joke. They get the power cables and trenches for new cabinets put in but don't have enough cabinets so end up filling in the trench again..... well planned!
End of my road is becoming Cabinet Hell.....currently old BT cabinet, VM Cabinet and now another 2 BT cabinets being stuck in, and I don't exactly live in a built up area.
